Polaris Rising by Jessie MihalikRead about another entry on the list.
We’re still in a pandemic so, escape way, way out of this world with Jessie Mihalik’s Consortium Rebellion trilogy. Book one, Polaris Rising follows a space! princess! on the run, as well as the outlaw she strikes a bargain with. Leia and Han vibes can commence from here on out. In Polaris Rising, Princess Ada chose to flee instead of accepting a political marriage. For two years, she’s survived on her own but then she’s caught and thrown into a cell with an alleged murder called the Devil of Fornax Zero. Infamous for having killed his squad, this space rake might be her only way to escape. When her jilted ex ruins everything by intercepting her ship bound for Earth, Ada makes a deal with the Devil. Literally. This rebel princess is everything I love from a heroine. The romance is ~hot~, the dialogue is snappy, and the series is complete and ready for you to binge.
