Alchemiya. Alchemiya, #1

Eugenia was born to privilege in the Ratna clan, nobility famed for their alchemical jewel production. Eugenia's a talented alchemist herself-but the patriarchy insists her less able brother is the heir to the family secrets and property. As if that weren't insult enough, an accidentally public tryst with another woman means Genie is shunned by polite society altogether. Enter the gorgeous Lord Oliver Plumtree, scion of one of the oldest alchemical families in Chrysopoeia and master of the foreboding Waldgrave Abbey.
But Lord Oliver is actually Olivia, and on the lookout for a wife-one who requires an escape from the same crushing social mores that have forced Olivia to masquerade as her own long-dead brother to keep her family's estate intact. Genie and Liv seem a perfect match from the get-go, and things heat up quickly between them. But before they can carry off their marriage of convenience, Waldgrave Abbey reveals more secrets.
Jealous Plumtree relatives and Liv's association with the Secret Society of Alchemiya, rumored to be a dark and sinister arm of the patriarchy, might just ruin Genie and Liv's chance at their unlikely happily ever after.
