Penguin Readers is a graded reading series for English Language Teaching (ELT) markets, designed for teenagers and young adults learning English as a foreign or second language.

Sometimes families are happy, and sometimes they fight. Sometimes life is good, and sometimes it is not easy. It is the same for the Marsh Lions in Kenya's Masai Mara, and for all animal families.

Penguin Readers is a series of popular classics, exciting contemporary fiction, and thought-provoking non-fiction, written for learners of English as a foreign language. The series is aligned to the Common European Framework and includes language activities that help develop key skills. 

Dynasties: Lions, a Level 1 Reader, is A1 in the CEFR framework. Short sentences contain a maximum of two clauses, introducing the past simple tense and some simple modals, adverbs and gerunds. Illustrations support the text throughout, and many titles at this level are graphic novels.
