I'm so lucky that my library is uh.maz.ing. They frequently order things within days of me asking for them! And because I requested it, I get first dibs.
Also for the digital argument, it sometimes helps along those set in their ways when I tell them I mainly read ebooks because holding heavy hardcovers flares up my carpal tunnel something fierce.
My automatic pre-order authors are:
Stephen King. I've read over 70 King books but not all yet, as he started publishing before I was even born. I can't list a #1 best book because he's covered multiple genres.
Joe Hill, his son. Everything I've read so far I've loved. NOS4A2 scared my pants off, but Horns is his #1 so far, imo.
Sarah J Maas, is only just now venturing out of the young adult genre. A Court of Thorns and Roses is her best SERIES but the first book is definitely not her best book.
Tessa Bailey ummmm this might be too racy for here but she writes smut and everything she puts out is phenomenal.
