The Heiresses

In Allison Rushby's Heiresses, three triplets—estranged since birth—are thrust together in glittering 1926 London to fight for their inheritance, only to learn they can't trust anyone—least of all each other.
When three teenage girls, Thalia, Erato and Clio, are summoned to the excitement of fast-paced London—a frivolous, heady city full of bright young things—by Hestia, an aunt they never knew they had, they are shocked to learn they are triplets and the rightful heiresses to their deceased mother's fortune. All they need to do is find a way to claim the fortune from their greedy half-brother, Charles. But with the odds stacked against them, coming together as sisters may be harder than they think.
