*MAJOR SPOILERS*

Redtail's Debt 5/5
This, from the offset, takes a much darker note than other Warriors books (or that could just be because I'm older). What makes it terrifying is that you go in knowing that Tigerclaw will kill Redtail and you experience frightened anticipation with every step towards that fate. "You owe me your life." There is so much pathos to be felt for Redtail in his anxious yet determined nature as he tries so hard to be the best warrior he can be amidst a sea of self-doubt and guilt. His kindness makes him a likeable character, even more so makes you root for him and sympathise with him when he is put in morally conflicting situations by Tigerclaw, knowing that his own life is at risk should he refuse to follow Tigerclaw.
He quickly became one of, if not my most favourite cat, which made his death all the more heart breaking. We only had a hundred pages with him, dammit!
"Redtail didn't drop his head in guilt or gratitude; he glared straight back into Tigerclaw's eyes. He felt like he was seeing Tigerclaw for the first time." That character development was very, very exciting.
Minor differences to the original canon aside, this is currently my favourite story in the entirety of the Warriors series! Love!

Tawnypelt's Clan 4/5
This is yet another character-driven tale, following the internal conflict of Tawnypelt as she struggles to fit in with Shadowclan after the time of the rogues. It is a realistic outlook, and a painful one, as some of her clan fails to see her outside of Rowanclaw's mistakes.
Shadowkit is also an interesting character, one I look forward to reading more of (haven't started the Broken Code series yet, waiting for the box set!).
The character dynamics between Tawnypelt, Dovewing and Shadowkit were cute and fun to read. Returning to the Tribe was also enjoyable.
I liked seeing Tawnypelt come to terms with what 'home' and 'clan' meant to her, and how she returned to Shadowclan and resigned as deputy. It was a fitting resolution to her story.

Shadowstar's Life 4/5
The premise of this tale is a look into the paradigm of the early time of the clans and the uncertainty of their future, where no cat knew what would happen upon a leader losing their ninth life. It also returns to discuss in depth the dynamics and relations between each clan after the First Battle, and attempts to keep up pleasantries and take care of all five clans, with the background plot of Skyclan's future showcasing this.
The plot is driven by the mystery of who attempted (and continued to attempt) to take Shadowstar's life, as well as the loss of Sun Shadow, and her resulting distrust in even her own clan, exacerbated by the need to appoint a new deputy. The extended metaphor/motif of amber eyes really pictured Shadowstar's anxiety and lonely predicament.
The ending had few flaws, mainly in the easy apology and forgiveness of Quick Water and Sun Shadow (she literally caused his death!).
All in all kept up the strong character study that was present in the other two stories, which I dearly hope to see more of in the next instalments in Warriors.
