(review of Books 1 & 2, without spoilers) 
 3.5 - 4 stars: Collide 
 4.5 stars: Stay 
 Collide was well-written, more masculine sounding than some of the books in this genre, which seem to veer more toward sounding like a M/F book with the same type of romance. While Collide maintained the masculinity to a certain extent, it was still a bit too sweet at times. 
 I enjoyed Collide as a feel-good read, but the pacing was a slightly drawn-out and slow after a while, with many redundant sex scenes. I almost took a break and read another book afterward instead of the continuance because it was a bit too hearts and flowers for me. But I'm glad I didn't, as I connected with the next book, Stay, more so. I was choked up a bit, and found it to be more realistic and faster in the pacing. Will be starting the 3rd in the series next.
