In this hardbound edition of Tom's 16th adventure in this series, he finds out that a newly classified exo-planet outside Pluto's orbit is about to have a close encounter with the return of Haley's Comet. The problem is that at such distances nobody can tell just how close. A visit to the Planet, Eris, is called for but he must first devise a ay to travel faster than he ever has before so the trip can be accomplished before the pass by. What he comes up with astounds even his father, and that takes a lot! Tom, Bud and their crew arrive in time to witness a catastrophic collision that begins the slow and inevitable break up of the planet. But, trouble is brewing as calculations show some of the debris will eventually drift in and possibly collide with Mars and the Earth. What to do? Nobody has ever tried to put an entire planet back together. This is a Humpty Dumpty exercise of planetary proportions.

In the twenty-first novel in this new series, Tom has defeated the Electricity Vampires and now wants something a bit less diabolical to take up his time. A new X-Prize is announced that intrigues him: fly a solar-powered aircraft, non-stop, around the globe in just 36 hours! That sort of speed will require an electrical powered jet, and that will burn up a lot of electricity. So, how can he manage to make what he needs by day... and still have enough to run at full speed at night? Might his recently discovered cousin in England, Thomasina Swift, be of some assistance? After all, she and her partner, Betty, have come up with an incredible solar cloth! Just as long as nothing ""exotic"" is used like one of Tom's Power Pods. Complicating things is a mysterious woman, and a deadly opponent, seemingly out to keep Tom from winning or perhaps from ever getting back home alive.

In his 17th adventure, Tom finds himself battling something his scientific knowledge has not prepared him for: personal tragedy! Having conquered several of sci-fi's most difficult problems, he is faced with a crisis that will test his abilities nearly to the breaking point. An incredibly close person is stricken with an inoperable tumor inside his head that will kill him in months, or an operation might do it sooner. At the very least, standard medical procedures would leave him with brain damage. When Doc Simpson proposes an impossible task, Tom finds that he must rally if there is anything to do to save the man. But Doc himself refuses to consider the treatment Tom has in mind when he finds what the inventor proposes is more like a living video game that serious surgery. Is possible to convince him to let Tom-an unskilled surgeon at the very best-perform the life-saving procedure? And, can Tom rally his emotional and physical strength long enough to make the operation a success?

The 18th book of the series. Like many people, Tom Swift-and his father, Damon-have dreamed of the days when the personal jet backpacks we've heard about since the 1940s become reality. When a movie director from Hollywood comes to Tom to create the real thing-he demands reality in his science fiction films with special effects-it intrigues the young inventor enough to see what he might create. It's a lot harder than it first appears! He must convince the director that his plans to have a 1940's period piece with leather jackets and bullet-nosed SCUBA tank-shaped rockets has to be updated to match what he believes might be deliverable as a real device. The suit is hijacked by the stuntman and ends up shooting him into space making necessary a search and rescue mission. In the end, it is up to Bud Barclay to save the day and fly the suit for the film. But, a sudden attack might be sending him on a collision course with death. Can Tom rescue his best friend and save the movie?

In the 20th adventure of this new series, Tom Swift finds a pleasant day test sailing a new yacht is turning into an attack from the sky. Out of nowhere a lightning bolt strikes his boat and sucks all power from everywhere. Not a freak incident, it seems to be more of a warning of things to come when a large power generating station along the East Coast is attacked next, with the same loss of electricity as if it had been siphoned back into the sky. This time, there is a great deal of damage and a near death. More and more power stations are targeted and now Tom must try to find out several vital things: Who is attacking? Why are they invisible and how do they manage that? What is their purpose in zig-zagging up and down the country hitting station after station? Not only is he broadsided by these attacks, he also finds out there is another Tom Swift out there; or rather a Tommy Swift. Together they work to uncover the evil attackers Bud Barclay has dubbed the Electricity Vampires.

In this hardbound edition of book 25 of the new series, Tom Swift is approached by a rich man with a dream of building a city that can float above crowded cities and land without creating more ecological woes. His dream is a flying platform on which such aa dream town might be built, and he believes Tom is just the man to realize it! The inventor struggles with finding a technology to make this happen before he must tell his benefactor it is "impossible." But, a chance discovery on an Internet site devoted to making fun on crackpot inventors and their ideas sets him on the path to an answer. However, nothing runs smoothly in Tom's world and he soon finds an old foe is out to track him down, hurt or kill him and Bud Barclay, and ruin the HoverCity. Who will win in this multi-battle showdown?

In this hardbound edition of novel 23 in this series, Tom must travel to Mars to find out just why the small moon, Phobos, has suddenly begun coming close to the surface. In fact it is coming down to lower and lower orbits that could, within months, endanger the colonists on the planet below. He first tries to use brute force and to push it back into higher orbit, but nearly loses several spacecraft in the attempt. So, he now is faced with finding out the why of it all before he can find a solution that won't mean simply destroying the moon. That, he fears, might backfire and do damage to the colony and the planet. He tries to find some answers with the aid of his Space Friends, but they seem to have disappeared from his life. Without their help he mounts an expedition of Phobos and finds about the last thing he might think of. Now it is a race against time to see if he can rectify the situation and re-place Phobos in its correct orbit.
