Little Tree, by Loren Long, Philomel Books 2015,
Terrible alliteration (by me) aside, I have long loved Loren Long's illustrative work. This book is another excellent example of his beautiful work.
The story itself is very sweet and simple, possibly a tad too simple, or possibly just right for the readers of this book. Either way, my seven-year-old son read it on his own and had no trouble understanding the message.
