Finance ✦ Penny’s Take
Perfect Ninja
Mary Nhin · 2020
72/100
👍 Worth It
Perfect Ninja lands a clear, age-appropriate message about perfectionism with enough humor to keep young readers engaged. It's light on story but heavy on usefulness as a read-aloud conversation starter for parents and teachers. Part of a proven franchise, so the execution is polished even if the depth is limited.
