The 3rd and 4th installments of the Warriors Series have basically been mostly about clan life and certain adventures:
In the third book, Fireheart's suspicions are getting stronger, and Graystripe's kits have arrived (along with a unhappy gift). But Tigerclaw's treachery only happens at the end.
In the fourth book, Fireheart is deputy of Thunderclan, and he struggles with new responsibilities, not mention his apprentice still has a heart in both worlds, until the end. Once again, it is mainly his little adventures about the Gatherings, wariness of Tigerclaw, and worries about Cloudkit. Nothing much happens, until, like the third book, there is big news about Tigerclaw right at the last page where he becomes leader of Shadowclan, the most horrific place for him.
(although it's the best position from his point of view, and clearly the Shadowclan cats are betrayed with their eyes and blind in their hearts!)
So, once again, we are left to puzzle until the releasing of the fifth book, a Dangerous Path, where I'm sure there will even more little worries and odd dreams among Fireheart's mind, and what his words are at the gatherings between him, Tigerclaw and Bluestar, who must certainly have troubles with her now. Not to mention, the Shadowclan will be back in evil paws once more, and there will be plenty of raids and attacks on Thunderclan.
On the bright side, I'm eager to find out what'll happen between Sandstorm and Fireheart! :) I hope they will grow happy together and Sandstorm will have kits to bring more honor into the clan! And Cloudkit will have half-brothers and sisters, not to mention him probably becoming a warrior.
Overall, this book was good, even though there aren't much drastic things happening, and I hope to see what other secrets come up!
