Yes! You sort of felt how the first book ended, it was open ended and more could be done. I love that more of the characters get explored here, especially Jason's ex girlfriend/fiancé, Marissa. And, that pain in the ass, Darren.
So much happens that by the end of the book you feel like you've read TWO stories! Halfway through, almost exactly, the story arcs wildly into thriller/suspense territory. Not necessarily horror more like action-suspense. Jason's family is very intense! The love developed between all the guys get complicated (Even more than their polyamorous relationship could be?) by an event that throws everybody into a panic and threatens all their lives.
Around chapter 13 this book turns into a page turnee that kept my breath bated. "What's gonna happen next?!"
Absolutely a must read.
