The letter Y has headed off a war between the consonants and vowels. Now, all the letters must learn to work together as they join Y in the search for his long-lost father--the mysterious letter X. Readers will learn common vowel teams, consonants blend and digraphs, silent letters, and more! The Building Blocks of English series helps readers master the fundamentals of the English language--from individual letters to advanced reading and writing skills--through fun and engaging graphic storytelling. Play-along questions make readers part of the story, and "show what you know" tests reinforce what they've learned.
