This is the second book by Tropper I have read in the last few weeks. What can I say, they were $1.99. As I said in my other review, he can be very funny. Based on this and This Is Where I Leave You, here are the elements of his formula:
The protagonist is 'damaged by love', "sensitive", from a dysfunctional family and laugh out loud funny about himself and those around him.
His mother is a bit flaky but very wise, if by wise you mean full of the most banal and trite pop psychology.
His love interest is also damaged, and in this book also "wise" like the mother. Sample wisdom- "All grief is the same."
He has a good relationship with his sister, who is attractive to stunning, caustically funny, and of course damaged by love..
You will have to suffer through the author's thoughts on 'how guys are' and 'men in the suburbs' and so on, presented as the main character's thoughts. They are thankfully usually brief....
