First let me say the banter in this book is off the charts awesome. Mark is that hilarious friend you want in your life that teases everyone and makes everyone laugh. THEN HE's the dirty talking lover who makes having a spare stash of fresh panties in your bag a necessity. DAMN DAMN DAMN #TeamMark100% 
 I was a bit confused at times. The story referenced past deeds that sounds like they had their own book but the author said this is a standalone. It is but knowing what books are in the series and what order they are read in would help. Audible says this is book 5 but goodreads doesn't have a book order. 
 I was kinda getting annoyed with Charlie because she was suppose to be kickass and she kinda was but when it mattered she had the drop on her. Either way i really really enjoyed this story. I want Mark.....lol. 
 (view spoiler)[ in the epilogue they have a 4yr old. I wish authors researched how typical children behave if they don't have children. A 4yr old speaks in full sentences. The 4yr old in this epilogue sounded like a toddler with 2 and 3 word sentences. (hide spoiler)]
