Heat Exchange is a fantastic firefighter romance by Shannon Stacey. Ms. Stacey has given us a book that is well-written and loaded with an amazing cast of characters. Lydia is called to come back to Boston because her sister needs time off from the family bar. Aidan is a firefighter and best friend to Lydia's brother. Aidan and Lydia's story is full of drama, humor, smokin' hot sexy bits and a bit of action. I enjoyed reading Heat Exchange and look forward to reading more from Shannon Stacey in the future. Heat Exchange is book 1 of the Boston Fire Series but can be read as a standalone. This is a complete book, not a cliff-hanger.
