Diana and Nubia: Princesses of the Amazons

Princess Nubia loves her mothers, their home on Themyscira, and all of her Amazon aunties. But she's still lonely sometimes. It's hard being the only kid on an island full of adults! She just wishes that things could be different. And then, one morning, things are different. There's a stranger sharing her bedroom...and the interloper Diana insists that it's her room! And their parents think they're both just being pests, they've always shared a room. What is happening?! Could it be that wishing into Hera's Ear on the night of the solstice worked? Will Nubia get to keep this strange new sister? Does she even want to?
