I think the conclusion of 'Arabella' wraps things up a little too neatly for my tastes, honestly. The whole last act feels rushed, like the author realized they had to tie up all these threads and just started snapping them into place. Arabella herself ends up with Lord Lexington after that whole misunderstanding about her being an heiress gets cleared up—turns out she really is just a vicar's daughter, and he loves her anyway. Which is fine, I guess, but it undercuts a lot of the earlier tension that made the book fun. All the side characters get their predictable endings too: the rakish brother reforms, the snobby society ladies are put in their place. It's a very conventional Regency romance finish.
What really bothers me is how the main conflict—Arabella pretending to be rich to save face—just evaporates. Lexington forgives her instantly once he understands her family's modest circumstances, and there's no real consequence or lasting awkwardness. I kept waiting for a more nuanced resolution, maybe where she has to earn back his trust or prove her worth isn't tied to money, but it just... happens. The final chapters read like a checklist. Still, I get why people enjoy it. The prose is charming throughout, and if you're in the mood for something warm and undemanding where everyone ends up happy, it delivers that. It's a comfort read finale, not a thought-provoking one. I finished it with a shrug, not a sigh of contentment or a gasp of surprise.
