Ok - so Einstein has to be my favorite Cyborg so far. I know lots of people are raving and excited about Seth coming out recently, but I'd been wondering how Einstein's love was going to come about. He is such a nerdy little guy (ok not so little maybe) and I love his logical approach to everything. When Bonnie throws his circuits out of whack he wants to go get checked for computer bugs. It was great.
Bonnie on the other hand, while very smart herself, has quite the little attitude. She's snarky and just a bit annoying and a whole lot of fun. I love her verbal sparring matches with Aramus (and they made me wonder about what his book is going to be like) and I think I even chuckled out loud at some of her antics a few times.
Their romance is pretty fast and a lot of the book is about getting her back to the Cyborg home safely. There was plenty of space fighting action - and plenty of action between Einstein and Bonnie as well. I love this series more and more every book I finish.
