Is Luck right for your level?
To recognise 95% of the running words in Luck, you need its 414 most frequent word forms; for 98%, the share at which most readers manage a novel without a dictionary, 452. The median English B1 book in our table needs 702 forms for 95%, so by this measure the book is easier than most for its level: number 4 of 21, easiest first.
A word form is any spelling that appears in the text, so “walk” and “walked” count twice, and names count too. These numbers are a guide to how much vocabulary the book asks for, not a test. The level itself was set by hand by our team. Before you commit, read one page of the free edition and count the words you do not know: the one-page test takes two minutes.
How does it begin?
I do not want to tell you his real name and titles. I will just call him Lieutenant General Lord Arthur Scoresby.
