Cara is almost 18 years old, she is starting her senior year in high school at another school, yet again, the only perk being that she gets to live with her sister. With her dad being in the Foreign Services, Cara has moved around so much and has been in so many different schools that she doesn't make a lot of friends and kind of stays to herself. After arriving in California, she takes her sister's car out to do a little sightseeing, has a flat, jumps a guard rail to try to find the person who owns the car she parked next to, and in the process ends up saving Will Mallory's life. She feels drawn to him but thinks she will never see him again, and tries to put him out of her mind. As fate would have it though, she attends an event with her sister for the University and who does she run into there, but Will Mallory.....and Will Mallory is as taken with her as she is with him. A strange man has been following Cara, and she sees him again when she is with Will, but Will doesn't want this man to see him. Then the strangest thing happens, and Cara's world is forever changed. She finds out there is a whole lot more to Will than she imagined. You see, Will is an alien, and not just an alien, but a hot swoon-worthy alien, and she finds herself falling hard for him.
I really liked Will. Not only is he hot, and I really love hot aliens, he really loves Cara to. She fills the empty void he has had in his heart for so very long. Their relationship does have its challenges though. Cara's sister Liv thinks Will is too old for her, the FBI is snooping around and suspicious, and to top it off, Cara's overbearing and bitter mother decides to show up. Then there is also the problem of Will being able to "hold himself together" when things get to steamy in the romance department. I loved Cara's sister Liv, and their relationship added a lot of humor to the story. As the FBI closes in on them, there is definitely a lot of action and drama. The romance in this book was really beautiful. Cara and Will have the type of love that endures despite what life throws at you, a forever kind of love. I thoroughly enjoyed this book. I loved the characters, the story line, and the romance. I thought the book was very well written and interesting, and would highly recommend it. I am looking forward to seeing where Kate Oliver takes the story from here. I really hope that Will will be able to hold himself together so that he and Cara can truly be together in every way. This was a great read, and if you love romance, hot aliens, with some action and a little humor thrown in, then Caterpillar is well worth checking out.
