And What Comes After A Thousand by Anette Bley

Otto and Lisa are special friends. Otto may be old, but he can still spit cherry pits, make slingshots and grow delicious raspberries. He and Lisa share a fascination with numbers, tell stories of brave Native Americans, and gaze at the stars.
But when Otto becomes ill and then dies, Lisa struggles to understand. Her rage, confusion and mourning are reflected in the illustrations as she slowly comes to know that, while people die, memories last forever.
This picture book, translated from the original German, is a gift to any young child and caring adult struggling to make sense of loss, particularly the loss of a loved and aging parent, grandparent or other special person. The illustrations, by the author, are especially skillful in their depiction of Lisa keeping company with Otto as his life ebbs away.

Lenny's Space by Kate Banks

Nine-year old Lenny is quirky, intelligent and in love with the world. And he comments on what he notices, what he loves, what he intensely dislikes.
His difficulty is that he does not know when sharing all this information is wanted, needed, or appropriate.
Lenny is lonely, he yearns for a friend; and he is brushed aside by his mother, his teacher, his fellow students. No one really appreciates his uniqueness or his struggle to figure out his world until he meets Muriel, a savvy school counselor, and when he encounters his first friend, a boy named Van.
Writing with wisdom, humor and poignancy, the author shows us the strange, troubled, and fascinating daily life of a boy who might be labeled in many schools "impulsive," "willful" , or "clueless."
Grandma's Book Letter recommends this book for parents and counselors of middle school youth for insights about children who look,on the outside,like Lenny but whose thoughts and feelings are unique.
