Brett  used his own experience with fire to fuel his career with ATF.  He's used to working pretty much on his own except for his dog, Blaze.

Gemma works with NICB and like Brett she's a lone wolf.  After a colleague used their relationship to usurp her investigation, she's vowed no more relationships with people she works with.  But her latest investigation intersects with Brett's. To further muddy the waters, Brett also has her family's mark of approval.  

The arsonist is escalating and getting bolder.

Brett is independent, smart, capable and just about the perfect partner. Gemma is independent, intelligent, stubborn, and a brilliant analytical & organizational mind. But trust does not come easy to Gemma. Blaze is an awesome K9 partner - he's brave, protective but a sweet and empathetic nature.

The romance is slow-burn in counterpoint to the fast moving investigation.  There are some real life issues interspersed with the story and they are deal with in a subtle and heart-warming away. These include: childhood trauma, mental health, misogyny and survivor guilt. The banter between Brett and his buddies is funny and true to life for LEO.

I received an ARC of this book from NetGalley & Entangled and this is my voluntary review.
