Marilyn Singer has written more than ninety books for children and young adults, including Tallulah's Tutu and A Stick Is an Excellent Thing, as well as the award-winning Mirror Mirror: A Book of Reversible Verse (Dutton). She loves to watch ballet and is an accomplished dancer of swing, foxtrot, and chacha. While researching the books about Tallulah, she sat in on a number of ballet classes for girls and boys at the Third Street Music School in New York City, which now puts on performances of the Tallulah books, featuring Marilyn as the narrator. Marilyn lives in Brooklyn, New York, and Washington, Connecticut, with her husband and several pets. You can visit her at www.marilynsinger.net. Truth be told, Alexandra Boiger really never took any ballet classes. If you ask her about her feelings for Tallulah and dance, she will tell you that the passion, strength, and humanity of this little girl are what spoke to her while doing the art for both Tallulah's Tutu and Tallulah's Solo. Going back to her own childhood, Alexandra felt about drawing exactly the way Tallulah does for ballet. Looking to the present, Alexandra sees all of Tallulah's emotions in her own little girl, Vanessa, who wants to be either a professional soccer player, storyteller, or actor at the school play--all equally enthusiastically. Alexandra was born and grew up in Munich, Germany. She now lives in California with her husband, daughter, and two cats, and has illustrated many picture books, as well as the Mrs. Piggle-Wiggle books. You can visit her at www.alexandraboiger.com.
