Womanizer by Katy Evans is the fourth book in her Womanizer series. It is told in mostly Olivia Roth's POV but we do get a few bits from Callan Carmichael. This book can be read as a standalone but the series is written on a progressive timeline so if you plan to read the series, read them in order or be prepared to be spoiled on other characters storylines. 
 Callan is best friends with none other than Malcolm Saint (Manwhore, Manwhore +1, Ms. Manwhore) and Tahoe Roth (Ladies Man). Olivia is Tahoe's younger sister. She is set to intern at Callan's company for a few months in Chicago and then head back home to New York. At least, that was the plan. This book had the best meet cute ever. I mean rooftop terrace, anonymous meetings, etc., etc. And then the bottom fell out from under Olivia when she finally realized who Hot Smoker Guy was! 
 The book isn't overly dramatic, it is just an endearing and amorous tale of two people falling in love and realizing that the plans you have set for yourself may no longer be the plans that are right for you. 
 I love everything I've read by Katy Evans so far and this is NO exception! Enjoy!
