The Necklace Trilogy is about Allie and Dash. The Tyler & Bella Duet is about... you guessed it: Tyler and Bella! Bella is Dash's sister from the Necklace Trilogy, and Tyler is Dash's ex-best friend. Both series can be read on their own, but their books must be read in order. Tyler & Bella are introduced in a big way in the Necklace Trilogy.

The Necklace Trilogy

A necklace delivered to the wrong Allison: me. I'm the wrong Allison.

That misplaced gift places a man in my path. A man who instantly consumes me and leads me down a path of dark secrets and intense passion.
 
Dash Black is a famous, bestselling author, but also a man born into wealth and power. He owns everything around him, every room he enters. He owns me the moment I meet him. He seduces me oh so easily and reveals another side of myself I dared not expose. Until him. Until this intense, wonderful, tormented man shows me another way to live and love. I melt when he kisses me. I shiver when he touches me. And I like when he's in control, especially when I thought I'd never allow anyone that much power over me ever again.
 
We are two broken people who are somehow whole when we are together, but those secrets—his, and yes, I have mine as well—threaten to shatter all that is right and make it wrong.

Tyler Hawk is a man with secrets and a dark past. A man who has known tragedy and betrayal. He wants for little, but what he wants is more power, a legacy that is his own, and not his father's. There are obstacles in his way, one of which is the scandal his father left behind and a will with certain demands.

Behind the scenes he is a man on edge, and only one woman sees the truth hidden beneath his strong will and dominant rule. Bella is somehow demanding and submissive, fiery and yet sweet. She can give him everything he wants, she just doesn't know it, not yet, but she will. If she'll just say yes and sign on the dotted line.
