Planesrunner (Everness #1)

There is not one you. There are many yous. There is not one world. There are many worlds. Ours is one of billions of parallel earths.
When Everett Singh's scientist father is kidnapped from the streets of London, he leaves young Everett a mysterious app on his computer. Suddenly, this fourteen-year-old has become the owner of the most valuable object in the multiverse-the Infundibulum-the map of all the parallel earths, and there are dark forces in the Ten Known Worlds who will stop at nothing to get it. They've got power, authority, and the might of ten planets-some of them more technologically advanced than our Earth-at their fingertips. He's got wits, intelligence, and a knack for Indian cooking.
To keep the Infundibulum safe, Everett must trick his way through the Heisenberg Gate his dad helped build and go on the run in a parallel Earth. But to rescue his Dad from Charlotte Villiers and the sinister Order, this Planesrunner's going to need friends. Friends like Captain Anastasia Sixsmyth, her adopted daughter Sen, and the crew of the airship Everness.

Can they rescue Everett's father and get the Infundibulum to safety? The game is afoot! (For ages 12 & up)
