Eternia Dragons is a book series designed for English language learners to get more confidence in their reading ability. Each book is designed to have easier and plainer language than is common in fantasy writing, without sacrificing the types of stories and scenarios that make that genre enjoying to read. Each book is a length that is long enough to feel "like a book" without being overwhelming. It aims to be a mix of short and easy enough that ESL and EFL learners won't be discouraged, while still having content engaging enough to keep them reading.
