4 out of 5 stars! 
 I normally don't really like contemporary or whatever, those kind of books but my gosh, THIS BOOK WAS SOOOOOO CUTE AND AMAZING! 
 I LOVE DON. LOVE HIM TO BITS. HE is sooooo sheldon. But looks like Colin firth in kingsman. And Rosie is just so patient and gosh, they fit each other well! 
 Its perfect for those people who wants cute, unexpected romance about a character like Sheldon from Big Bang Theory. 
 This is book 2! I think I enjoyed this more than the first book, The Rosie Project. 
 IN this book, DON Tillman takes on preparation of fatherhood. 
 Definitely recommend to people! Read this! 
 SPOILERS BELOW. 
 I LAUGHED OUT LOUD WHEN DON FOUND OUT HE'S GOING TO BE A FATHER AND HE WAS PREPARING, AND HE FILMED CHILDREN PLAYING AT THE PLAYGROUND AND HE GOT ARRESTED FOR SUSPECTED PEDOPHILLIA HAHAHAAHA. 
 And how he's trying to help Rosie by instructing her on what to eat all. GOSHHHHH. 
 LOVED how he drew Bud on the tiles to keep track of his growth. I also loved how he's such a good friend to everyone, and tries his best to solve their problems. When his marriage was in peril, his friends repaid him by announcing to everyone how he d helped them. 
 My heart was broken when Rosie told him that he wasn't cut out for fatherhood. Or so she thought. Then when she saw the tiles, and the lesbian mothers project video of him playing with a child, she burst into tears because I think she realised her almost mistake. 
 I swear she is the luckiest person ever. 
 ALSO ANOTHER LOL MOMENT WAS WHEN HE WAS ON THE PLANE TO TRY TO CONVINCE ROSIE TO COMEBACK AND THE FLIGHT WAS TURNED AROUND BECAUSE THE AIR MARSHALL'S THOUGHT THAT HE WAS A TERRORIST. HAHAHAHAHAAHAHAH. 
 SO many ups and Downs in life and it was sooooo super interesting to watch a character like DON to take on life, especially fatherhood. DON is just a lovely character, so unique and because of that he gets into trouble that normal people don't.
