AU. Harry, Ron, and Ginny send themselves back in time to avoid the destruction of everything they hold dear, and the deaths of everyone they love.

This is the companion novel to Backward With Purpose. I'd read that one first. This story is complete; the sequel has begun.

Petunia married a biochemist, and Harry grew up reading science and science fiction. Then came the Hogwarts letter, and a world of intriguing new possibilities to exploit. And new friends, like Hermione Granger, and Professor McGonagall, and Professor Quirrell... COMPLETE.

Take a deep breath, count back from ten… and above all else – don't worry! It'll all be over soon. The world, that is. Yet for Harry Potter the end is just the beginning. Enemies close in on all sides, and Harry faces his greatest challenge of all - Time.
