Emaricas "Emma" Hope Prescott is a newly-single mother striving to adjust to the daunting task of solo parenting. Her career as a licensed nurse supported her family well over the last few years, but now she finds it nearly impossible to provide for them after the smashing demise of her rocky marriage. While struggling to give her children the normal life she's promised them, another curve ball is in hurled her direction. A forgotten face from the past calls on her to make good on a vow made on the deathbed of a dear friend. Emma sees no choice but to thrust herself back into the gray world of casinos and eerie neon lights she once thought to be forever part of her past. She hopes to provide a future for her children while flying under the radar of a very shady set of characters attached to the benevolent world she left behind. But, the darkest shadow from her past is unwilling to let sleeping dogs lie. Set in the maelstrom of today's society, things begin to sizzle under a sultry Texas sun as the tarnished FBI agent, James Talbot, searches for redemption in what is presumably a simple surveillance case. However, an unexpected spark threatens to ignite the familiar flames of a hauntingly bloody nightmare. When a malevolent figure sets out to eradicate the one woman able to seal his fate, James must convince his irritatingly bewitching assignment to accept his help. As Emma decides whom she can trust, she must also release the burdens of her past before her fate-and the fate of her innocent children-comes crashing down around her. The question is: Will the young, defiant mother make yet another promise? And how dearly will she pay for it?
