The Deceived Ones - Judith Krummeck

Displaced by the Russian invasion, Vira, carrying little but her precious viola da gamba, is a refugee in the Uniting for Ukraine program. When she is physically attacked soon after her arrival in the United States, the terrifying experience prompts her to hide in plain sight by passing as her twin, Sevastyan, until he is able join her. 

Orson has been commissioned to write an opera for The Twelfth Night Festival, but he is suffering from composer's block. Not only that, his muse, Isabella, has inexplicably withdrawn from all performing. During a chance meeting, Orson discovers the extraordinary musical talent of Vira, now passing as Sevastyan, and it gives him the jolt of inspiration he needs. Hoping that Isabella will be as intrigued as he is, Orson sends "Sevastyan" as his emissary to persuade Isabella to sing in his opera.

In this love-quadrangle seen from multiple points of view-some poignant, some hilarious-the myriad misconceptions that result from Vira's deception are woven into themes of migration, sexuality, and diversity.
