Publishers Weekly Best Illustrated Books 2012
"DaCosta debuts with a bang—or, more accurately, a whisper—in this atmospheric account of a ninja's stealthy midnight journey. It's gratifying to see Caldecott Medalist Young flex his comedic muscles, and his collages are as masterful as ever. But what makes this story so outstanding is how seriously it takes the young ninja's mission, right up until the moment his secret is revealed."

Horn Book Book of the Week and interview with artist Ed Young! "On the surface, this is a simple story, a glimpse into the imagination of a child and the tender relationship between mother and son. Young’s art, however, perfectly pairs with the minimal text.... A spare text loaded with tension paired with evocative illustrations make this a bedtime story that will be asked for again and again." (November 2012) and recommends Nighttime Ninja as a great Halloween story: "Illustrator Ed Young’s cut-paper and cloth illustrations imbue mystery, beauty, and emotion into the story as it moves from the boy’s imagination to reality." October  2012

New York Times Book Review "....The novice, DaCosta, in her first picture book, seems nonetheless experienced with such nighttime [ninja] apparitions." 10/14/2012

Nighttime Ninja 
Barbara DaCosta, illus. by Ed Young. Little, Brown, $16.99 (32p) ISBN 978-0-316-20384-5. "DaCosta builds her debut on the scaffolding of the suspenseful adventure that turns out to be make-believe. Illustrators of stories like these sometimes hint at what’s coming with comic artwork, but Young’s (The House That Baba Built) collages are deadly serious as he enters fully into the boy’s fantasy....Artwork as fine as Young’s might overshadow the story, but DaCosta crafts her spare text carefully and with humor. Her ninja language tracks the boy’s actions right up to the moment he grabs a spoon. The depth of feeling Da Costa and Young give to the boy’s fantasy makes this a standout. Ages 3–6." 07/23/2012
