What I haven’t seen anyone talking about (on Tumblr at least) is that the Neverfive snippet takes place at Christmas, which means we’re going back to having almost a full year of events in the book!
(Also presumably the snippet takes place closer to the end?)
So here is my proposed timeline for the rest of the series…
Neverfive: Spring - around Morrigan’s 15th birthday
Neversix: Spring-Summer of Five (before the snippet I was imagining Neverfive would end in Summer and the climax of the book would happen at the Nevermoor Bazaar lol)
Neverseven: Autumn-Winter of Five
Nevereight: Spring-Summer of Six
Nevernine: Autumnn-Winter of Six, the end of Unit 919’s final year as junior scholars (and the last year they have a hometrain). Morrigan turns seventeen.
Knowing that Morrigan will definitely not be nineteen by the end of the series, I think this is what will happen (ish).
