I read Django Wexler’s The Forbidden Library back-to-back with Sophia McDougall’s Mars Evacuees. They’re very different books, albeit aimed at the same age-group (9-12).
The Forbidden Library is a fantasy novel set in a version of Earth around the turn of the 20th century. Alice Creighton overhears her father having an argument with a fairy. Soon after, her father leaves on a journey, his ship sinks, and Alice is brought under the guardianship of a man called Geryon, who almost certainly doesn’t have her best interests at heart. She learns that she has magical powers in a dangerous and forbidding library, and struggles to learn the truth about what really happened to her father.
Mars Evacuees is a novel set in a near-future Earth that’s been invaded by aliens, the Morrors. Alice Dare, daughter of ace pilot Stephanie Dare, is evacuated to not-properly-terraformed-yet Mars with a group of other young adolescents. But things go wrong on Mars, and Alice and a small group of others must make a dangerous journey alone across the planet to seek help.
Both of these books are an awful lot of fun, although Mars Evacuees is really more My Thing. I recommend them both.
