How long does it take to read The Mysteries of Udolpho?
At 1,065 pages, The Mysteries of Udolpho is a doorstopper. Expect about 19 hours 20 minutes of reading to finish it, based on 250 words per page and an average reading speed of 230 words per minute. A fast reader will go quicker; a careful read (or reading in a second language) will take longer.
At 30 minutes a day, that is about 39 days of reading. At the median pace of Vread readers, 72 pages per reading day, it takes 15 reading days.

In Vread, The Mysteries of Udolpho is split into 30 checkpoints, one every 36 pages or so. At each checkpoint, a question covers the passage you have just read: a correct answer validates the step, and your progress moves forward like a training plan.
The challenge: validate all 30 checkpoints through to the last page. No giant quiz at the end, no summary to copy out: short questions along the way that prove the book was actually read. It also works as a reading quiz to check your understanding before a test.
Also available in French on Vread.
