Larceny & Love (Larceny & Moonlight Series) by Ima Ghoul

Ervina, a thief and child of a travelling troubadour and a distant mother, has spent most of her adult life on the streets subject to the whims of other ne’er-do-wells. That is until she targets the wrong mark, a noble who goes by the name of Asherton.

Once arrested, she experiences the harsh reality of prison life and harassment for being one of the dreaded Velshere. Asheron offers her a choice: pretend to be his estranged fiancée and retrieve a valuable, or rot in prison.

As the attraction builds between the pair, Ervina tries to deny her feelings. Can she complete her task without falling for the kind and gentle lord who has a secret of his own?
