Firelight (Stargazer Ranch Mystery Romance Book 2) by Suzanne Cass

Emily Hillenbrand believes every day is a gift and should be lived to the fullest. But she carries a secret that could destroy her plans to survive on her own terms.

Tom Coulston is hiding from a past heartbreak. He’s drawn to Emily’s vivacious nature; he’s beyond salvation, however, and is no good for this sweet-natured woman.

Together, they’d make an explosive combination, if only they let themselves feel.

The recent fires at Stargazers Ranch have them all on edge, and Tom is desperate to protect Emily from a suspected arsonist. He can’t go through the agony of losing another woman he loves. When she agrees to leave the ranch, little does Emily know she’s walking straight into danger. 

Tom will have to overcome tragedy and risk it all as the arsonist stalks them both and everything goes up in flames…
