Have you read the Harry Potter books (by J. K. Rowling)? What do you think of them?
PrevNode LinkI read the first four installments. My favourite was the first because it didn't take itself as seriously as the next three. I stopped after reading the fourth book, because I noticed that, except for the first one, they all ended up making me ecstatic (see "hypomania" (= "below-mania")), which I preferred to avoid.
The books I read were captivating enough for me to persist in (although they seemed to have a slow start), often funny, contained interesting supernatural elements, and appear to have been written in an English register that was accessible enough for a foreign speaker like me (with a few unrecognised words that I looked up) yet not too dumbed down to be annoying (like e.g: the Simple Wikipedia).
