Trace of Grey
Nursing White back to health for the past two months has prevented Grey from taking on any new projects. She's more than ready to get back to work when White offers her a simple surveillance job.

The basic op turns up something from the past, putting extra pressure on White, and cutting Alex off the elite need-to-know list.

Everyone has secrets, but some are more guarded than others.

Fragments of Grey
Betrayed, miserable, and estranged from White and Associates, Alexis Stanton entertains thoughts of payback—but she can't sever the last few ties she so desperately clings to. Revenge is not the answer.

Tragedy opens the door for her return to White after she completes one last assignment for his competitor, a temporary job she'd taken while she figured out a few things. But what she discovers changes everything, and now Alexis knows: revenge is the only answer.

Edge of Grey
When you take away a woman's soulmate, you take away her purpose.

When White is taken from Alex, she finds a new purpose. Cast aside by her former partners, she will hunt down everyone responsible for her loss and Make. Them. Pay.

Harder... darker... at the edge of sanity. But still the world's most notorious assassin. Penumbra will have her reckoning.
