Query: If you're a fan of unhappy endings and torture, this is the book for you!

I kind of enjoyed the beginning of this book. Interesting characters, kind of a unique take on the whole time travel thing, historically accurate, etc... It was a bit repetitive but I muscled my way through it thinking there would be a great payoff at the end. Boy was I wrong! I hated the way this book ended with such a passion that my heart rate still raises just thinking about it.If you like characters that learn from their mistakes, go no further than book one because they keep repeating them.If you like your books to have an end, then don't start this series. There is NEVER an ending!
