In the fourth book of the Extinction Point series, the earth has been decimated by the aliens who have begun to colonize it. Emily Baxter’s first concern is her son Adam, but the child had eyes that are speckled with red. He is the first posthuman child born after the apocalypse. With Emily’s husband off on a scouting trip, there is no one to defend her when she’s accused of a heinous crime. The only way to prove her innocence is out there in the world that is no longer hers, or any humans. She sets off her her stepdaughter and faithful dog, to prove her innocence and reclaim her humanity. This series has been a totally different take on the popular post-apocalyptic fiction so popular. I was always terribly worried about Thor (the dog) being injured or killed.
