Kate DiCamillo meets Lemony Snicket in this darkly comic novel about two sisters who learn they are each others' most important friend.

Imagine two twin sisters, Arabella and Henrietta—nearly identical yet with nothing in common. They’re the best of friends . . . until one day they aren’t. Plain and quiet Henrietta has a secret plan to settle the score, and she does something outrageous and she can’t take it back.

When the deed is discovered, Henrietta is quickly banished—sent to live with her eccentric great-aunt Priscilla on Chillington Lane, where black cats roam the dark rooms and tonight’s menu is fish-head stew! Suddenly life with pretty, popular Arabella doesn’t seem so awful.

And, though she’s been grievously wronged, Arabella longs for her sister, too. So she hatches a plan of her own and embarks on an unexpected journey to reunite with her other half.

The Trouble with Twins is an adventure and a comedy—a tale of the power of unlikely friendships, the bond between sisters . . . and the way a bit of mischief sometimes sets everything right.
