Elizabeth Olsen is an award-winning actress known for her role as Wanda Maximoff in WandaVision and the Marvel Cinematic Universe. Just like Hattie Harmony, she uses tools like mindful meditation and yoga whenever she's feeling a little anxious. She lives in Sonoma, California with her husband, Robbie Arnett.

Robbie Arnett is a writer and musician who loves to go for a hike when he's overwhelmed. This is his debut picture book with his wife, Elizabeth Olsen. He lives in Sonoma, California, where he bangs on his drums when he feels anxious.

Marissa Valdez worked as a preschool teacher before writing and illustrating children's books. When she needs to feel more present, she sketches in her notebook. She lives in Houston, Texas, with an impressive collection of gnomes.

STAR AUTHOR: Elizabeth Olsen garnered national attention when she starred in the Marvel Cinematic Universe as the Scarlet Witch. Now with WandaVision, her own hit show on Disney+, Olsen has gained even more of a devoted following. She, along with her boyfriend Robbie Arnett, have created an original picture book series with staying power and they are eager to promote.

RISING ILLUSTRATOR: Ambitious Girl, written by Meena Harris, is Marissa Valdez's debut picture book (Little Brown, 2021), and with Valdez's clever illustrations and vivid color palette, we know she's one to watch.

CHARACTER-BASED APPROACH TO WELLNESS: The children's wellness market has skyrocketed and wellness for kids is here to stay. This series takes a fresh approach through a strong character who teaches kids how to self-soothe during moments of anxiety, as opposed to the more abstract and poetic books for kids in the market that might feel harder to apply to real life.

REAL ANXIETY TOOLS: Hattie Harmony gives science-approved advice on how to stay calm via breathing exercises and other mind-body practices.

PLAYFUL TONE: The fun and vibrant illustrations and humorous narrative turn the serious topic of anxiety into a sweet and helpful story with a kid-friendly protagonist.

BACK TO SCHOOL: The first book in the Hattie series focuses on the first day of school, making it perfect for this promotional window.

SEQUEL: The second book will publish in Summer 2023.
