Actually, he spends most of his time hoping no one notices his strange habits—he calls them Zaps: avoiding writing the number four, for example, or flipping a light switch on and off dozens of times over. He hopes no one notices that he’s crazy, especially his best friend Max, and Raya, the prettiest girl in school. His life gets weirder when another girl at school, who is unkindly nicknamed Psycho Sara, notices him for the first time. She doesn’t just notice him: she seems to peer through him.

Then Daniel gets a note: “I need your help,” it says, signed, Fellow Star Child—whatever that means. And suddenly Daniel, a total no one at school, is swept up in a mystery that might change everything for him.

Chasing Secrets by Gennifer Choldenko

San Francisco, 1900. The Gilded Age. A fantastic time to be alive for lots of people…but not thirteen-year-old Lizzie Kennedy, stuck at Miss Barstow’s snobby school for girls. Lizzie’s secret passion is science, an unsuitable subject for finishing-school girls. Lizzie lives to go on house calls with her physician father. On those visits to his patients, she discovers a hidden dark side of the city—a side that’s full of secrets, rats, and rumors of the plague.

The newspapers, her powerful uncle, and her beloved papa all deny that the plague has reached San Francisco. So why is the heart of the city under quarantine? Why are angry mobs trying to burn Chinatown to the ground? Why is Noah, the Chinese cook’s son, suddenly making Lizzie question everything she has known to be true? Ignoring the rules of race and class, Lizzie and Noah must put the pieces together in a heart-stopping race to save the people they love.
