A Matter of Trust - The Silicon Beach Trilogy, #3

Venture capitalist Vlad Snezhinsky excels at two things: making money and being a dad. Still struggling through a bitter divorce, he has zero interest in starting a new relationship. That is, until he meets Klara Lazarev. Klara doesn't have time for romance. She's too busy forging her own path in life: scrambling to finish her senior thesis, applying to grad school, writing innovative software in her spare time.  Besides, she's been burned before.
She refuses to let it happen again-especially with a man who seems to have trouble remembering their first disastrous encounter. But when a shocking murder throws their world-and their hearts-into chaos, discovering the truth becomes more than a matter of trust.
