I love time travel stories. And I love history. This book had a lot of promise. The main character, Max (who’s female), is witty and loveable. The book is full of action. There are lots of jokes about historians. (Historians in this series carry blaster guns and pepper spray, and have been known to do battle with a T-Rex.) But there are far too many characters to keep track of, and far too many of them die in combat. I had difficulty telling them apart. This book is the first of a rather long series, but I doubt I’ll continue with the others.
