I originally received an e-book copy of this book from Library Thing, lost the link,then ended up buying the actual book because I wanted to read it so badly.Awesome book! This is the third book in the River series, but can also be read on its own. I read Eximere, book four, first and am now working my way back to the earlier books.This is such a cool series. Good characters and an intriguing plot, this is a very good read. It is quick to get through because you don’t want to put it down. I loved the creative problem solving. And at times the descriptions are simply spine-tingling. Well-written and a joy to read. I highly recommend the series.
