I picked up a physical copy (thrift store, for the LFL) and saw this had high ratings and was first in the series ...  I was going in knowing this was for younger readers, actually looking for an "easy" read.

There are SO many names (kitty characters ... Ferncloud, Dustpelt, Squirrelflight, Stormfur, Graystripe, Leafpool, Firestar, Spiderleg, Cloudtail, Brightheart, Ashfur,  SpottedLeaf), and the repetition ... HollyKit, JayKit, LionKit ... then the "kit" becomes "paw" and there's already Berrypaw, Hazelpaw, Bramblepaw, Cinderpaw, PoppyPaw, Mousepaw ...

I don't know if, even this being the start of a new series, if a reader really needs to already be familiar with the origin story, the world (as this is actually a spin-off, third series in this world)? It just wasn't grabbing me.  If it was too young?

3rd person/Past tense.
Basic chronological chapters (25 of them) ... I got through chapter 9 before calling it.
