The Pieces of Me (Geeks of Caltech #2)

"I'm so lost in the dark I can't see. Will you be willing to put together the pieces of me?" - Shiv
Shiv is a former hacker with no conscience and even less desire to mingle with people.
Until he meets his pretty and cheerful surgeon neighbor, Naina.
All he wants is to run his bar in peace and forget all the darkness in his past...and maybe bask in the sunshine of Naina's open heart.
But, then that past comes knocking and Shiv has to make a terrible decision.
One that impacts the life of his oldest friend. So, this grumpy loner has no choice but to confide in Naina.
Unfortunately for Shiv, when he begins to trust Naina the dark of his soul craves the light in hers. While his desire for her grows out of control.
And that puts Naina in the crosshairs of those who would harm Shiv...Can Shiv save Naina while knowing he is the true threat to her life?
