We have a little bookshelf for Keely that sits next to the trunk that holds all her things. Each year for Christmas, my parents get her a new book in her stocking (so the stocking's not empty) that we put in her shelves (it also has little brother's book "Someone came before you" and big brother's book "We were going to have an baby but got an angel instead"). When the boys have questions or we just need a minute 'with her', we can go to her shelf to read them. Last year, they put "God Gave Us Heaven", etc.
My mom was having a hard time finding the right one for this year so I did some searching and we ordered "I see the moon" by Kathi Appelt and it came in today. It's just perfect. Gorgeous illustrations, adorable story. Definitely a tearjerker but in a good way. The little girl in the illustrations even looks to be around 3 years old <3 Although Keely had blonde hair (and I'm thinking it probably would've stayed that way had she aged). The last page is about God bringing her home safely.
Here's a link that has excerpts and you can see the gorgeous illustrations: http://www.amazon.com/gp/product/0802852262/sr=8-1/qid=1288304709/ref=olp_product_details?ie=UTF8&me=&qid=1288304709&sr=8-1&seller=#_
