Diana and Nubia: Princesses of the Amazons — Shannon Hale

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?
