The Grandmother Hypothesis

As far as Irish American, anthropology major Orla Oliver is concerned, every man in her life is an ass. Her father, her college tutor, and others that… well that she'd rather not talk about, even to the shrink she's being forced to see.
When it comes to emotional support, Orla knows to stick to the women in her life: her darling-albeit-emotionally-damaged mother, her best friend Shondra and most of all, Mamo – her beloved Irish grandmother whose opinion Orla rates above just about everyone else's.
So when a stranger named Dan contacts Orla through the Ancestry website suggesting that her deceased great-uncle is actually alive, Orla is torn. She doesn't consort with strange men. And the one thing her forward-looking Mamo hates to discuss is her own family history.
But the possibility of reuniting Mamo with her long-lost only brother is just too tempting for Orla to ignore. And what harm can come from just meeting this Dan guy and finding out more? Cheered on by Shondra who truly believes in happy endings, Orla lets her curiosity overrule her misgivings and so begins a journey that Orla could never, ever have imagined. Turns out some family trees should really never be climbed.
