River of Fire

Really good opener for the series. Sensible to make it quite short coz often these books can just go on and on and on (for reference, the last Warriors book I read was Leopardstar's Honour).
I thought what they did with RiverClan was very bold. I didn't really like the ending but it was very exciting and does make me look forward to reading the next book. Apart from that, Frostpaw isn't a particularly interesting protagonist but she works.
Sunbeam's conflict is a bit boring but I like her as a character.
Flamepaw is actually really interesting to me though. His conflict with being Firestar's descendent was really compelling and felt quite self-aware given how much Warriors has previously prioritised Firestar and his kin. I also find his scepticism at the rules of clan life to be really refreshing and found his naming ceremony really interesting.
Really good start for the series! I'm excited to see where it goes from here.
