Six books, all set on one stretch of coast: three standalone books and the Harrow trilogy (sample).
The shelf
Every book stood side by side at the same scale, oldest on the left. The thick one is The Harrow Ferry; the short one is the only paperback original, Small Hours.
Drawn to one scale: each spine is as thick as the book (0.07 mm a page) and as tall as its edition, hardback 234 mm, paperback 198 mm. The red headband is the new one.
Every book, newest first
What each one is about in a sentence. The Harrow novels are best read in order.
