Zak's book is listed as #13 in the Seals Brotherhood series, but it stands alone just fine. I haven't read any of the other books in the series, and I never felt "lost". It did really make me want to catch up to the rest of the series though, because all of the characters are great. And I would love to know more about this whole SEAL team.
My warnings for this book are graphic sex, language, some violence and deep emotional issues. Some of the violence is combat related and could be a trigger. But the thing that really got me about Zak's story, was the emotional tension and issues. Deep stuff. Ugly cries. I had to set the book down several times and calm down. But it was worth it. Very worth it. I love Zak and Amy.
