The Water and The Wild by K.E. Ormsbee
Lottie Fisk lives with Mrs. Yates since her parents are dead and her only friends are Eliot, a boy who is very sick, and a mysterious letter-writer. But strange things are happening on the island and then a door in her favorite apple tree opens to a strange world.
I would call this a modern, middle-grade Alice in Wonderland with a timeless feel. Lottie lands in a weird world where she meets three sprites her age (Ollie, Adelaide, and Fife) and they go on an adventure to find Ollie and Adelaide's father, who was kidnapped. The Water and The Wild is whimsical and quirky and the characters are the right amount of interesting and flawed. I think more couldn've been done with this story if it was young adult rather than midle-grade, but I still really enjoyed this book as it is.
If you like fantasy and reading children's books, you'll like The Water and The Wild.
Lois Lane Fallout by Gwenda Bond
Lois Lane is starting a new life in Metropolis. She's trying to stay quiet, but in her new high school a group known as the Warheads is making life miserable for another girl at school. They're messing with her head via a high-tech immersive video game and Lois wants to solve the mystery.
I loved this book so much that I read it in one day. Lois Lane is snarky, intelligent, determined, and keeps her cool. She's on the road to being a reporter and is friends with a guy in Smallville who she talks to online, but he refuses to tell her who she is. I kept turning the pages so fast while reading this; I had to know how the Warheads were messing with this girl's head and if Clark was going to tell her who he is. It's fast-paced, clever, and a fun ride. I need the second book in my hands like yesterday.
If you like strong female characters and superhero origin stories, then you'll like Lois Lane Fallout.
