Chronologically, Yellowfang's Secret takes place during the same time period as Bluestar's Prophecy and Crookedstar's Promise, and before the original Warriors series (Into the Wild).
Crookedstar

The book after Crookedstar's Promise is Into The Wild, as of now. Crookedstar's Promise ties in with Bluestar's Prophecy, and soon to be in the same era is Yellowfang's Secret. So, Bluestar's Prophecy is after Crookedstar's Promise, then it leads to Into The Wild.
