Midnight Girls is a sapphic, YA fantasy about witches that tear and eat the hearts out of princes. If you want true morally grey characters, this is it!

Marynka is the servant to one of the three different powerful witches and is at her beck and call when she asks her to bring her a prince's heart. She represents Mid-day, where the other two witches and their servants represent Morning and Midnight. Maynka has a bitter rivalry with the Midnight servant, who always beats her to the hearts, much to her grandmother/witch's chagrin. The Mid-day and Morning witch decide to partner when a Prince is discovered in the city with a pure heart, the most powerful and tastiest. Marynka and Beata (Morning servant) travel to the city, not knowing that Zosia is also going after this heart.

This was such a fun rivals to lovers story, although I wouldn't even say the whole book is romance forward. The world-building, magic, names are all Polish inspired and I listened to the audiobook and it is very evident in the writing. The magic was so fun and so intriguing with it based off the time of day! It's dual-POV, so you see both Zosia and Marynka's perspectives and the individual things they face. Zosia longs for freedom from the witches, while Marynka only wants to earn her grandmother's love.

It definitely has dark themes and content, which I love in a YA. If anything I think I would have enjoyed seeing this in a more adult setting as well. The dialogue, specifically from Marynka definitely tends to be more YA/immature. I very much enjoyed the romance, and I loved the ambiguous ending.
