GABE HAD FORGOTTEN how exhausting Tío Duties could be. Since it was his first time visiting Nikki’s kids at their home, they’d taken it upon themselves to be good hosts. Seven-year-old Oliver had endeavored to show Gabe every single Lego set he owned, along with a detailed commentary on the “special features” of each one, and nine-year-old Lucy had insisted they play all the outdoor games she could think of, from tag to water guns to pony rides. That would’ve been okay, except Gabe was the pony, and the kids had taken turns leaping onto his back and screaming in his ear to run faster.
