Myra Cohn Livingston was born in Omaha, Nebraska. Her family moved to California when she was 12 years old. She studied the French horn from age 12 to age 20, becoming so good that the Los Angeles Philharmonic invited her to join them when she was 16 years old. She had other plans. She knew she wanted to write.
Wanted to read some poetry for Easter morning, and found this on Internet Archive (archive.org). Livingston's collection, nominally published for children, contained both secular and religious poems (appropriate for a religious holiday that has crept secularly into the broader world; see: Animal Crossing's Bunny Day). Included are some poems by authors who I thought of as novelists for children: Joan Aiken, Zilpha Keatley Snyder. "An Easter Present" by X. J. Kennedy was my favorite among them poems.
A mediocre collection of Easter-related poems. Rather dated graphics. Not particularly impressed by the quality of the content - can see why it was in my library's book sale.
