Aliens come to earth offering help and more to humans. These are not your typical two legged, upright aliens no these are like spaceships. You can travel in them, and some humans go on a kind of foreign exchange program traveling out into the universe with them. How cool is that ? Oh but it gets so much better, they can communicate with humans, in ways that I'm not going to tell you but they are awesome. The book centers on one alien, and his honors (humans) two very different girls. This alien is a kind of runt of the litter, and on his last chance mission. Yes, there is a tug on the heart strings. One of the girls is not a follow the rules type and quickly crosses the line with questions and bonding with her host more than she should. There are space fights, dramatic encounters, emotional breakthroughs, and revelations that shock. I loved it, I want to hear it on audio now. It was so visually written it would be a fabulous movie. Please make the movie somebody. I was on the edge of my seat through the whole book. it had a slight Star Trek vibe going- bonus. The characters where all so well developed I was felt for all of them. I'm shocked I'm not a SciFi reader, I expected to not like this. It ends with a cliffhanger so be ready to grab the next book.
