The Timberlakes loaned us this book recently and we enjoyed reading the story with our kids. Based on the DISC personality profiles, the characters are a lion, an otter, a golden retriever and a beaver. Together these "four best friends" go on a quest for some keys, and each animal plays a "key" role in helping to find them. As they go about the adventures, their individual personalities become clear.
About half-way through the story we stopped and asked the kids if they could tell which of them were like which animal. Colsen immediately nailed it for all four of them: Strider is the otter, Rayna is the beaver, Colsen is the golden retriever and Miles is the lion.
I get a kick out of realizing we have one of each type, and it's also been eye-opening as we realize what motivates each child. I look at them all a little differently now. And I hope they all continue to go on adventures together as friends, appreciating each other's special gifts and quirks.
