Praise for Pepper’s Rules for Secret Sleuthing

“Exciting and fast-paced… A fun debut that is notable for its thematic depth and queer characters.” – Kirkus Reviews

“A great modern read-a-like for Harriet the Spy and other mystery classics like Nancy Drew and the Hardy Boys. Hopefully, there will be more adventures from Pepper and her friends in the future.” – School Library Journal

“Irrepressible and lovable, Pepper joins the ranks of the best kid sleuths—and shows that sometimes the heart is the toughest mystery.” – Eliot Schrefer, author of National Book Award Finalist Endangered
