Not only is this book so wonderful in teaching twin children what it is like to be a twin with having "twin power", the Authors are truly amazing as well!!! My best friend is currently pregnant with twins and she is doing this all on her own, with no partner. We were both in shock when finding out it will be twins, but also super excited! She did not want to find out the genders of the babies until they are born, which drove me crazy! She surprised me one day and told me I could look onto her records to find out myself, as long as I didn't tell anyone. I thought this was so thoughtful, and wanted to something special for her as well. I found this book online and thought how great would it be if I could get the Authors of this book to sign a copy for her. Not knowing if I would get an answer, I gave it my best shot and reached out. They answered back almost immediately and told me they would be honored to! I purchased the book and they made sure to send it to me right away, since these babies could come at any time! They not only signed it, but added the sweetest personal message to her, and even included some of their handy "tips for having twins". I am so excited for my friend to open my gift, as it is currently wrapped and in her hospital go-bag waiting for her to open after as she delivers the babies. I give this whole experience 5 stars, and I can only hope there are more stories about Sebastian and Simone to come soon!!!!!!!
