★★½... I got ALL I WANT FOR CHRISTMAS IS A WEREWOLF because I'm a sucker for wolf shifters and the author is NTM. It met my expectations—a quick holiday-themed story with a bit of sex. Several standard werewolf/shifter tropes were present and the ending was utterly predictable but for a freebie, I can't complain.
However, I think that the story would've been stronger if it had focused more on the current mating as opposed to rehashing in detail what went wrong with Gavin's first mating. Also, the three-week jump forward in plot was a bit jarring. With more individual introspection instead of interaction, it was hard to buy their love/HEA beyond the metaphysical mating connection.
ALL I WANT FOR CHRISTMAS IS A WEREWOLF turned out to be about 30 Kindle pages/screen (taking into account the 150% line spacing and larger TNR font). There were one or two minor plot inconsistencies and editing/proofing errors were within the "we're all human" range. Overall, it was written well enough so that I could consider trying this author again in future. But probably only if the next story was more developed and longer.
