Aru Shah #4: City Of Gold

The fourth fast-paced fantasy adventure starring aru Shah! Aru has just made a wish on the tree of wishes, but she can't remember what it was. She's pretty sure she didn't wish for a new sister, one who looks strangely familiar and claims to be the sleeper's daughter, like her. Aru's biggest question, though, is why every adult she has loved and trusted so far has failed her. Will she come to peace with what they've done before she has to wage the battle of her life?.
