Burn by Callie Hart is the third book in her Blood & Roses series. A dark and twisty book full of tension and desire. 
 While I wanted to hear more about Lacey, the story really couldn't have gone there. Picking right back up inside the compound where Sloane and Zeth are biding their time, waiting for Sloane's sister to appear, we now encounter the previously mentioned motorcycle club and their villainous leader. More on that topic would be way too many spoilers though. 
 A compelling and absorbing story for any fan of dark romance - Callie Hart has created some amazing characters and my only wish is that she would write faster and ease the ache of WAITING (sigh). 
 I highly recommend this series.
