A Lion to Guard Us: Lucy’s book review

This book is about three little children.  There names were Amanda, Jemmy, and Meg.  They sailed on a ship to go to America and to find their father in Jamestown.  Their father had a door knocker that people thought was made of gold.  Dr. Crider is a doctor that helped them get to the boats and he fell overboard on the ship.  Their ship got shipwrecked at an island and they  built a tiny village.  They built two ships and sailed to Jamestown.  They found their father at Jamestown.  My favorite part was them getting to find their father. 
Love, Lucy.
P.S.
This book was the best book in my life!
