Inherit the Stars: A Cosmic Romantasy (The Solar Sovereign Series) by Amy Ressa

She was born in the shadow of a tyrant. Now she must rise into the light - or be consumed by it… Cyra is a gifted healer with an addiction to using her own dangerous magic. When her mother vanishes and a royal summons drags her into the militant court of House Mars, she’s forced to confront the truth she’s spent her entire life hiding - about her power, her bloodline, and the legacy she was born to inherit. Lord Zevran, the brooding and battle-worn ruler of House Mars, suffers from a mysterious affliction only Cyra can soothe. Their nightly healing sessions begin to blur the line between duty and desire, binding them in ways neither of them expects. But when a masked stranger made of darkness itself saves her life, Cyra is drawn into a web of secrets, seduction, and betrayal. With a Conclave looming and the solar system teetering on the edge of destruction, Cyra must decide who to trust, who to love - and whether to embrace or destroy the monsters she’s heir to. Perfect for fans of Sailor Moon looking for a spicier adult version, you’ll love this book if you like cosmic magic, deadly trials, court intrigue, multiple love interests, queer representation, and tropes such as one bed, slow burn, forbidden passion, and "burn the world for her."
