Treasure of the Ton by Tamara Gill

A scarred spy, a daring debutante, and a love too dangerous to resist.

Ezra Ashworth, Lord St. George, never intended to return to London’s glittering society. Scarred in body and soul from his years abroad serving the Crown, he has no desire to fulfill his duty as Earl—or to take a wife. Especially when the last woman he loved perished under his protection. But when a shadow from his past threatens Lady Evangeline Ravensmere, Ezra has no choice but to step back into the world he abandoned to ensure her safety.
Newly under the guardianship of her brother-in-law, the new Duke of Ravensmere, Evangeline is determined to forge her own path—one that leads to the kind of love she longs for. But when the enigmatic and wounded Lord St. George returns to society, she suspects he harbors more than just old wounds. His secrets tempt her, his presence challenges her, and soon, she finds herself drawn into his dangerous world…and into his arms.
