Oh yes, I go through phases! Way back when, I only read historicals. I think I burned out on them, because now I only read a very few. Also, this genre seems to have gone through the PC thing, and I don't care for PC books at all. I am down to only 2 authors that I read now in this genre.
I do like the heavy suspense books too. Karen Rose types, with suspense that is chilling and leaves you scared to turn off the lights! It seems like when life is bad, these books go to the back burner for me. So I am playing catch up now!
I do like to hang on to books from series of 3, and read them together. Although I hate it when books 1 and 2 come out back to back, then we wait another 6 months for book 3. I'm sure the publishers have a reason, but besides SpamFilter me off I'm not sure what it is!
I am not reading as much either. The other night I picked up 3 books, before settling on one to read. Part of the problem is I have too many books to read. The TBR pile is over 1000 again, and I try to keep it under that. I guess half the fun of being a book addict is making sure I have a great collection, that is well organized and I can always lay my hands on all the books. But the downside is determining what to read next. Too many choices!
I keep a reading journal for every year, and one thing that comes through loud and clear is that I like series books (it's hard to find books that stand alones these days), and are (1 )contemporary, or (2) romantic suspense. Another thing I see is RS authors who are going more towards suspense and away from romance have fallen off my radar. Gotta have my romance!
Since I left the workforce, I thought I would read more, and it's been the opposite. I like to do so many things, that my reading has fallen off. I did not watch TV for years, so evenings were set aside for reading. Now Monday - Thursday I watch my fave shows and cross stitch while I watch TV. I volunteer a lot at the hospice and with our dog rescue organization, and spend lots of time in the summers in the gardens. You never know what tomorrow will bring, so I try to do something every day that I enjoy and looked forward to doing when I was able to retire early.

This is something I truly hope everyone of you can do some day! There should be some reward at the end of our working days.
