These "Let's Read About" books are a very good way of introducing your young readers to Biographies. Although this one about Pocahontas is a little 'off' of what truly happened (unlike the other books in the series are pretty accurate) this one is pretty accurate and will give an 'opening' to read more about the Indian Princess. Easy to read a couple of sentences per page and most of the wording isn't large words where an advancing reader couldn't read on their own.
Let's Read About-- Pocahontas (Scholastic First Biographies) by Kimberly Weinberger an early reader, that introduces American history as a classroom resource and biography of historical figures.
