OK. This book is a big jumbled mess. On paper, reading what it's about - a group of Legion of Super Heroes from the future stuck in the past is a cool idea. That got me a bit intersted. Then I actually read it - or tried to. Being a new reader to the LOSH, I'm a bit confused on what's going on. The action starts right away. The team members all sort of do their own thing for various unknown reasons that I'm confused about and can't keep tract of. It gets hard to keep tract of everyone. Then all of the sudden the team gets the bad guy (the reason they went back in time), who may not be a bad guy (who knows), and tries to go back home. It happens fast and forgetable.
All in all - this book is bad, real bad - 1/5.
