This might legitimately be my favorite book series. It's hard for me to just review this one book, because you really need to read them all. Each book is basically a different genre of storytelling, which is fascinating.

A group of friends is sucked back in time, and all they want to do is get back home. They make it back, but of course everything is different, and now they need to fix it.

You've got a time travel novel with an added search for a serial killer from the future. The science is very enjoyable, though you might have to read it twice to completely grasp the rules. Completely worth the reread though.

Benjamin Travers currently sits at the top of my list of favorite characters in literature. Intelligent and quick witted, he slides right into the time travel world.

I have recommended this to anyone that asks for new books to read. Every time they tell me that they've never heard of it. My response? “Read it, and then you'll never forget it.”
