Winter Romantasy like “3 Wishes for Cinderella (1973 czech version) and “Narnia” (2005)?

With christmas approaching I'm looking for something to satisfy my childhood nostalgia!

I feel like for most Europeans the movie Three Wishes for Cinderella (1973 version!) is a well-known gem that everyone and their mother (literally) watches around christmas.

I've been searching for a book that gives off siminar vibes. I'm also a big fan of the first Narnia movie so I'd really want to see those combined!

I'm looking for the following in particular (doesn't have to check all the boxes):

• winter scenery
• (winter) fantasy world that has a war/conflict going on
• MMC fights alongsinde FMC
• magic is used by the FMC to fight (swords would be fine too)
• horse riding
• adult MCs
• romance that is light and slow burn (no dark romance please)
• fancy ball gowns (and balls where they dance)
• pfeferably with a printed version available
