Jane Seymour has ink-stained fingers, one elusive bird, and a single season standing between her and independence. If she can finish A Living Encyclopedia of Avian Wonders before she's forced to take a husband, she'll never need a man's permission to live her own life. All she needs is one bird: the bearded tit. The ridiculous, moustached little creature has evaded her sketchbook for eighteen months. She does not require the Viscount who catches her when she falls out of a tree in Hyde Park. She does not require his crooked smile, his four-year-old ward, or his country estate where the bird she's been chasing supposedly nests. And she most certainly does not require the slow, devastating realization that the rake the ton whispers about is the most devoted father she has ever seen — or that the secret he carries could destroy them both. But when fires begin burning across his land and Jane finds love letters hidden in his study, she must decide what she's willing to risk: her heart, her independence, or the family she didn't know she wanted. Tree-climbing heroine. Devoted rake. Devastating secret. Her Viscount's Secret is a steamy Regency romance with a headstrong heroine, a brooding Viscount with a life-altering secret, and heat that builds from slow burn to wildfire. Intended for readers 18+.
