This was hard for me to rate. I'd give it 3 1/2 stars (rounding up to 4). There were parts I loved and parts that made me go 'huh?'.
I loved the main characters and I did enjoy Seth's fantasies with Sahara...very hot!
Also, this is part of a series (Mastering Toby was the book before this one), but considering I haven't read the first book, this can be read as a stand-alone.
