The night I met them irrevocably changed my life.
The Devil’s Den.
The notorious MC known for boozing and sharing their women between brothers.
That life never appealed to me. Not until I met Walker, Hudson, and Levi.
I’ve found myself sucked deeper into their life as each day goes by.
It was never supposed to be more than a small favor, but you know what they say.
Play with the devil and get burned by his flame.

REVIEW:  THE DEVIL’S DEN by Cala Riley is a stand alone, contemporary, adult, ‘why-choose’ erotic, romance story line set in the multi-authored 31 DAYS OF TRICK OR TREAT. This is Zoologist Esme, and Hudson, Walker and Levi’s reverse harem relationship.

NOTE: Due to the nature of the story line premise, there may be triggers for more sensitive readers.

Told from four first person perspectives (Esme, Hudson, Walker and Levi)THE DEVIL’S DEN follows the building relationship between Esme and the three men with whom she will fall in love. Having caught her boyfriend Troy in bed with her best friend Kimberly, Esme was struggling with issues of self esteem but when she discovers another set-up wrapped in yet another betrayal, our heroine takes charge, literally landing in the lap of a biker at a bar. Walker agrees to play along, thus embarking on a lifelong relationship with his two best friends, and the woman with whom they will fall in love. The past refuses to let go, refusing to give up and walk away, and in this Esme finds herself facing down her demons on more than one occasion.

The world building focuses on the ‘why choose’ relationship between Esme, Walker, Hudson and Levi. Levi and Walker are bisexual, and have been in a relationship for as long as they can remember: Hudson is the third friend, who loves his ‘brothers’ equally , and all three are hoping to find one woman with whom to share their lives. THE DEVIL’S DEN focuses more upon the relationship than the MC lifestyle . The MC consists of several clans and polyamorous relationships, each searching for one woman to share. Esme, as well as Hudson, Walker and Levi all grew up in the foster care system, and in this they share a kindred spirit with their own heartbreaking past.

The relationship between Esme, and Hudson, Walker and Levi begins as a pseudo rescue in the wake of the ongoing betrayal in Esme’s personal life.Worried that the woman with whom they are falling in love will choose only one, Walker, Hudson and Levi each have personal time and a chance at seduction, ensuing Esme will fall in love with all three. The $ex scenes are erotic, and provocative without the use of over the top, sexually graphic language and text.

The secondary and supporting characters are limited. We are introduced to Esme’s former friends Kimberly and Ambers, as well as ex-boyfriend Troy: co-workers Charlotte and Susie.

THE DEVIL’S DEN is a story of love and loss, obsession and betrayal, family and friendship, acceptance and love. The fast paced, character driven premise is thought provoking and inviting; the romance is spicy and unconventional; the characters are energetic and charismatic,
