In my opinion, this book is like FSoG but the male character shows his intention in getting his girl stuck with him. 
 This book may have something similar to FSoG but in its own way. Between FSoG and This Man, FSoG end the book with Mr Grey deliver punishment to Ana but in This Man (view spoiler)[Ava fund out that the Manor is a sex club and the persistent of Jesse to try and explain the things to her and ends up drifted apart (hide spoiler)] 
 Overall, this book has a own easter egg that I found and I wonder if you found them too. 
 How many time does this book contain the word 'this man' 
 How many '-ish' can you find?
