August 1815. The war with France is officially over, Napoleon’s an exile on St Helena, but Europe is still a very dangerous place to be.

Kidnapped and held for ransom at nineteen, ducal heir William Ravenwood knows the only person he can rely on is himself. Now part of a spy ring that includes his friends Nicolas and Richard Hampden, he’s the smuggler known as The Raven, a ruthless agent who specializes in rescuing hostages and prisoners of war from captivity.

Raven longs to discover the fate of his colleague, Christopher ‘Kit’ Carlisle, who’s been missing, presumed dead, for over two years. He’s also equally determined to stay away from the one thing he knows is dangerous to his health – the bane of his life, his best friends’ infuriating and provocative little sister, Heloise.

Heloise is a brilliant code breaker, one of the English government’s most valuable assets. She’s also loved Raven for years, but considering that he rejected her at sixteen, before her face was scarred rescuing her brother from an icy river, she’s certain he doesn’t want her now, despite his outrageous flirting.

But when Heloise decodes a message that proves Kit is alive and a prisoner in Spain, Raven realizes she’s in grave danger. With French agents determined to silence her, he’ll do whatever it takes to keep her safe – even if that means taking her to Spain with him as an unwilling hostage.

As they face French deserters and Spanish freedom fighters, Raven and Heloise try to ignore the simmering attraction that’s been building between them for eight long years. The differences between them are striking but they’ve always had a strange underlying bond. Heloise might be scarred outwardly, but Raven’s wounds are all on the inside. He knows he’s not worthy of her love—a shadowed Hades pining for sun-kissed Persephone—but he’s not above showing her passion for the short time they’re together.

A master at decoding complex messages, Heloise finds Raven frustratingly hard to read, but as their lives hang in the balance she’s determined to unravel his secrets and unlock his dark, elusive heart…
