Sayeski’s Unraveling Dyslexia is the consummate source for the most comprehensive information on dyslexia to date. Sayeski has masterfully created a resource for both readers just embarking on learning about dyslexia and those who think they have it unraveled. Chapters segue seamlessly from one to the next like a narrative, and the chapter conclusions helpfully consolidate the information and reaffirm the insights. Sayeski offers a historical review of written language development and reading instruction. She describes the multidimensional complexities of reading, theoretical models of reading, and the individual differences in readers that influence reading trajectories and instructional decision-making. She brilliantly demystifies structured literacy, addressing both word recognition and language comprehension, as depicted in the Simple View of Reading model. Masterfully, Sayeski incorporates the neuroscience of the reading brain, phonology, grapheme-phoneme correspondence, comprehensive phonics, orthography, text types, semantics (vocabulary and morphology) knowledge-building, and discourse writing, and she identifies evidenced-based approaches to instruction. Impressively, in just 200 pages, Sayeski provides a master class that does not disappoint. In addition to special education and reading instructors, book clubs and parent groups should take a look at this treasure trove. Essential. All readership levels.
