(3) YA Anxiety-sufferer Stefanie Brons hates the diagnosis "selective mutism": it makes others think she has control over her inability to speak. (Her narrative voice, however, is wonderfully sardonic and plainspoken.) When Steffi befriends cute new boy Rhys, who's deaf, and communicates with him through sign language, she sees herself anew. Thunder is the rare, authentic novel that dives into the day-to-day of debilitating anxiety.

(3) PS Kangaroo and Koala both enjoy blowing bubbles, but Koala is too shy to talk to Kangaroo or climb out of her tree. However, when some of their bubbles stick together to form a bubble monster, Koala musters the courage to help her new friend. Delicate watercolor and pen-and-ink illustrations depict the rosy-cheeked animal tykes' sweet friend-courtship and keep even the bubble monster looking more cute than scary.

(4) PS Illustrated by Greg Pizzoli. An interactive read-aloud features a pink dinosaur who loves birthdays, hats, dancing, and painting, but who is also very timid. The direct-address text leads the reader through a number of suggestions ("Go on, say hello") that result in inane mistakes ("Your voice startled him") and occasional silliness. The illustrations are bold and vibrant, but the text often misjudges the reader's responses.

(3) K-3 Illustrated by Richard Jones. After Caro and her mom move to a new home, the lonely girl finds an indoor playmate in the Snow Lion. When they spot some kids out the window, the lion encourages Caro to make human friends. In this subtle book's deftest touch, the white lion is barely visible against Caro's home's white walls--a gentle intimation of his being imaginary.
