Still need to read The Cloud, but I did read Helena vol. 1 & 2 and I really enjoyed them. Basically it's about Simon who is head over heels in love with Helena, ever since high school. But she is one of those girls that is a little too pretty. Simon is now an adult and when he sees Helena again after many years she has become even more beautiful than he remembered. But what if he were to pay Helena 1000 euro a month to spend 3 hours a week with him every Thursday afternoon. Not for sex, just to get to know here a little better...
The premise sounds a little cheesy and Pretty Woman like, but that's not the case. I did some short reviews of both volumes on goodreads and rated the books 4/5* https://www.goodreads.com/MartinNL
