The notification from Ancestry.com blinked on Elias’s phone, and he nearly dropped his morning coffee in surprise. He’d done the test as a lark, a silly thing to do on a Tuesday afternoon. Now, it was informing him he had a close relative he didn't know about. A giddy bubble rose in his chest. He clicked on the message, anticipation zinging through him.

He slammed his laptop shut and grabbed his keys, grinning. Time to visit his parents, or, as it turned out, the people who raised him. He whistled the tune of a ridiculously upbeat pop song as he drove, tapping his fingers on the steering wheel in a rapid-fire rhythm.

The look on his mother’s face when he announced he needed to “discuss some *gene-pool shenanigans*” was priceless.
