Rosenthal had long delighted children with her books including "Duck! Rabbit" and "Uni the Unicorn," but it was her loving missive titled "You May Want to Marry My Husband," that most recently resonated with adults.

She was diagnosed with ovarian cancer in 2015, and knew she didn't have much longer.

She wrote the would-be personal ad for Jason Rosenthal and also noted her fatal diagnosis. It ran earlier this month in The Times.

"If you're looking for a dreamy, let's-go-for-it travel companion, Jason is your man. He also has an affinity for tiny things: Taster spoons, little jars, a mini-sculpture of a couple sitting on a bench, which he presented to me as a reminder of how our family began.

"Here is the kind of man Jason is: He showed up at our first pregnancy ultrasound with flowers. This is a man who, because he is always up early, surprises me every Sunday morning by making some kind of oddball smiley face out of items near the coffeepot: a spoon, a mug, a banana.

"If he sounds like a prince and our relationship seems like a fairy tale, it's not too far off, except for all of the regular stuff that comes from two and a half decades of playing house together. And the part about me getting cancer. Blech."

Besides children's picture books, she also wrote journals and memoirs, gave TED talks and radio commentaries and completed short films and YouTube videos.

She began her writing career in the 1990s, after vowing to quit her marketing career.

She and her husband raised three children. She had completed a picture book called "Dear Girl" with her daughter, Paris, while she battled cancer

Her prose was upbeat and lyrical, including her tribute to Jason. He deserved love after she was gone and she hoped "that the right person reads this, finds Jason, and another love story begins," she wrote.
