To complement the 6 books on the Life of Jesus in the Bible Alive series, Christian Focus Publications have just added 4 books on the life of Moses. Carine Mackenzie has (as always) written a biblically accurate set of books with just enough detail for the intended age group. This series is pitched at around 4-7 yr olds. I would recommend these to anyone who is looking for books for this age group.
Moses the Child, Kept by God
Moses the Shepherd, Chosen by God
Moses the Leader, Used by God
Moses the Traveller, Guided by God
