Clockwork Heart — Mandy Rosko

A Great War has wreaked havoc on the world, but that's nothing compared to what Brandon did to her. Betty Bel-Grant lives every day preparing for revenge. She uses her father's plans and builds machines of destruction that no one has ever dreamed of, waiting for the day when the automaton returns. But when he finally shows up again, this time minus the glowing green eyes, he pleads with her to believe that his clockwork parts had been sabotaged; his machinery had been hijacked to make him attack. The excuse is convenient, but unbelievable, because why would her Uncle Jimmy want to kill their family? Betty's determined to find out the truth, and to see to it that the person responsible pays. Even if it's the man she loves.
