This book engages with trauma in a way that young children can relate to. Being told from the perspective of a pear tree that survived 9/11 but didn't know what was going on before/during/after but had to survive nonetheless makes this something that my kids (four of them 8 and under) were able to relate to. Everyone experiences trauma at some point. 9/11 was a lot of trauma for the whole US all at once, and being able to reflect on that from the perspective of a tree in an illustrated (not graphically violent) story format gives kids an accessible way to start understanding this traumatic series of events. I would highly recommend this book for any parent who has struggled with how to talk about 9/11 with their kids. The post-script of the book has a more detailed and well-written explanation of the events of 9/11 which was helpful for my older children who wanted to learn more after reading the book.
