In editions 2 and 3 of Cracking Comprehension Years 1-6, published in 2013 and 2016 respectively, we wrongly attributed the text for The Winged Horse to the author Rosalind Kerven. This is incorrect. The Winged Horse as featured in Cracking Comprehension editions 2 and 3 is not the work of Rosalind Kerven. We apologise for any inconvenience caused.
