Lara recommends Foxheart by Claire Legrand

Magic, mischievous strange beasts, ominous dark forces, time travel--this book does it all, and does it well. Quicksilver is a refreshingly real main character who is used to doing things by herself and in whatever way she likes, until her destiny is thrust upon her by characters both terrifying and bizarrely familiar. Haunting, enchanting, and just macabre enough, this book surprises you with every chapter, and ultimately shows how powerful a little compassion and empathy can be.
