I liked all of these, from various romantic sub-genres:
The China Garden by Liz Berry - When Clare goes with her mother to an English estate with dark secrets, she begins an unexpected journey. The ensuing story spins itself into many layers, featuring mystery, fantasy, and romance, all centered around an ancient family feud of which Clare is unwittingly a part. This novel is very rich in detail with a lot of historical and mythological references, so it is not for the faint of heart. For those who like deep stories with realistic romance, this is an outstanding read.
Dustlands by Moira Young – In a post-apocalyptic future, 18-year-old Saba’s twin brother is stolen by black-clad riders. When tough-as-nails Saba launches a relentless search to recover him, she must fight for her life in gladiator cages, overcome enemies both creature and human, and learn to trust others for the first time. And try as she might, she can’t help but fall for the charming scoundrel Jack, who just may understand her more than she knows. The author tells Saba’s story in a raw first person format that blows you away. Must read for dystopian lovers!
Going Too Far by Jennifer Echols - Meg's desire to escape her backwater town and smothering parents leads her to a dare that runs her afoul of the law. She is sentenced to join rookie cop John on night patrol to better appreciate the importance of maintaining law. Meg despises John because he seems content to remain in their small town. John disdains Meg, because she is so hateful of the community. As they strive to understand each other, both extend their boundaries - and of course, fall in love.
The Grand Sophy by Georgette Heyer - Set in Victorian England, young but energetic Sophy is taken in by her aunt Lady Ombersley. She soon discovers that her aunt's family is in desperate need of her talent for setting everything right. One step at a time she fixes the family messes, wins their hearts, and finds love everlasting. A joyous story with a strong romantic thread.
Catch Me Falling by David J. Nix. As a caged display in a traveling freak show, 18 year old Crissa endures stares, taunts, and whispers of a terrible word from others - Human. But folks come by thousands to hear her do what no other can do. Sing! In a ‘what-if’ world where prehistoric Humans fell extinct and Neanderthals inherited the earth, Crissa's Human face marks her for abuse and grisly death. When a stranger with a face like hers appears, she flees with him from those seeking her death. Crissa’s flight carries her toward the mysteries of a murky past, her unusual face, and the wonderment of love and belonging.
I Capture the Castle by Dodie Smith - Seventeen-year-old aspiring writer Cassandra lives with her family in a crumbling English castle rented when times were good. Her optimism is challenged daily by her hopeless but beautiful sister, brooding father, and disassociated step-mother. Her mundane existence is turned suddenly upside down when the wealthy Cotton family takes over a nearby estate. Written in the 1940's, this book is a modern classic often compared to the works of Jane Austen.
Jellicoe Road by Melina Marchetta - Taylor finds herself the leader of her boarding school's Underground Community, whose mission is to battle their counterparts at an all-male Cadet encampment and the public high school. For two decades the three factions have waged a game of negotiation, pranks, and sometimes physical violence for control of paths, places, and facilities. One problem: Taylor might have a crush on the leader of the Cadets. The author weaves in a back story about how the whole war started, and how Taylor is unwittingly tied to it. Romance, action, mystery, and plot twists, this is just a great story.
