The Sun and the Star

 I really loved this book! The characters go through hardship and work on their relationship throughout the entire book, and it was really nice to see. Like how we get to see Will and Nico's differences and see them getting frustrated with one another, yet still caring for each other despite that. I also really liked how Will had issues in Tartarus and had to use memories, music, and even a Sun lamp to stay well in Tarrarus due to being a child of Apollo. I also absolutely adore Small Bob and the Coco Puffs, so that helped me really love this book.
