Everything comes at a cost.

When Brodie's sister dies, her death kills his future...

Certain she was murdered for her research and work on building a time machine, he must use her device to go back in time and save her life. But nothing is ever so simple. Betrayed by those he thinks he can trust and with alternate timelines piling up, Brodie quickly discovers that every trip back changes something.

There's no going back to the way things were before she died; no matter what, he loses someone.

A truth he doesn't learn until it's too late. Can Brodie live with the changes he's made to history? Is he strong enough to decide who lives and who dies in this twisted tale of time travel? Is love an option when everything's so messed up? And with friends like these, who needs enemies?
