Sweet Filthy Boy by Christina Lauren is their first book in the Wild Seasons series. 
 Three besties on a weekend getaway to Vegas celebrating College graduation find themselves entangled in the lives of three very different men. This story focuses on Mia and her new French lover, Ansel. 
 A one-night stand in Vegas is just what Mia thinks she needs, but when Ansel causes her to start viewing her life in a different light, she starts to question everything. 
 A beautiful story of learning to face life head on and embrace love when it happens. A HUGE fan of Christina Lauren already, this series just cemented that further.
