Embers (Blaze #3)
Erika Chase

With her love life in ruins, Kate McDonald comes back to San Francisco, hoping to bury herself in work, in writing - in anything but the mess she's struggled through. Unable to commit to her high school sweetheart Sam, or her lover, the damaged writer Gabriel, she's lost them both.
Or so she assumes.
Even as Kate tries to step into a bright new future (one without any confusions or complications) , the past returns with a vengeance. It has no intention of letting her go - and every time she gives into it, Kate will find herself a little more seduced by what she thought she'd left behind...
Embers is the third in the ongoing Blaze series of adult romance novels by Erika Chase.
