The following are not puzzle books per se, but you might find them interesting...
Chess Tactics from Scratch: Understanding Chess Tactics By Martin Weteschnik.
This is not your typical tactics book, but instead is a relatively advanced course in chess tactics and combinations, focusing on methodologies for analyzing tactics, for the intermediate player and above. The uniqueness of the book is that the author attempts to systematize the process of examining any position in order to determine if certain conditions exist which would make the position amenable to a given type of tactic. The tactical themes are arranged by chapter. For additional advanced tactics training check out "Learn Chess Tactics" by John Nunn, "How to Calculate Chess Tactics" by Valeri Beim, and "Forcing Chess Moves" by Charles Hertan.

i finished the woodpecker method around a year ago, and found it much more useful than online puzzles (you need to calculate multiple lines, like in a game.) I’ve been looking for new books, but have had a hard time finding any good puzzle collections for my rating range (I tried calculation by Aargaard, and it’s too advanced)
would anyone have any recommendations for something around the same level as the intermediate puzzles in the woodpecker method, or for 1850 USCF level?
