PICTURE BOOKS
Picture books with multiple, distinct hooks, clear/concise writing, and original concepts. I am open to working with both authors and author-illustrators in this space.

• Heart-warming picture books that celebrate community and resilience
• Whimsical stories that honor individuality and what makes us unique
• Stories that highlight culture, traditions, and belonging
• Silly, quirky stories with few words and unique storytelling
• Inventive and clever nonfiction, particularly STEAM themes and lyrical, narrative nonfiction that sings
• Gentle storytelling that tackles tough topics like grief, racism, chronic illness, divorce, or anxiety
• Humorous stories that stretch the imagination—puns are a plus!
• Holiday books with a fresh take or a unique twist
• Retellings of lesser-known fairy tales or legends
• Horror! Creepy picture books that allow young readers to explore fear, tension, and the unknown in a safe and fun way
