What a freaking gorgeous gem of a romance. I adored "The Full Moon Problem" to absolute bits: it made me laugh, it made me swoon, it made me blush, but it also, especially, made my brain blissfully quiet and happy for a few dreamy days.
If you look up "soft" in the dictionary, you'll find this book as an example. It's literally a warm embrace or a cup of tea during a cold afternoon in book form. It's soft, lovely, romantic, packed with feels, found family and lots and lots of healing, care and love.

This is my first time reading a Kay Claire novel, and I'm already (im)patiently waiting for their next masterpiece: I thought this book was going to cure me from my looming reading slump, but instead I got a book hangover. I already miss Felix and Declan and I have a Nimblyford-shaped hole in my heart. I never wanted to leave this amazingly cozy, small-town world.

Felix and Declan were fantastic characters.
Felix stole my heart the first time he appeared on page: I loved how warm and kind and open-hearted he was, and I also loved that although he's pretty confident in general, he still has his moments of vulnerability and insecurity. I also loved the fact that he was a yapper and a horny mess of a man: I love dark and broody protagonists, but horny, sunshine-y disasters will always have a special place in my heart too.
I also loved that he was confident and happy with himself and his body: you can see he's gone through quite a lot in life, but seeing him happy, whole, healthy, at peace, was wonderful. The romance genre definitely needs more trans rep in general, but I think it also needs joyful trans rep too and protagonists like Felix who have managed to embrace themselves fully, happily, proudly. Gah, that man made me emotional, and I'll miss being in his head.

Declan was a wonderful counterpart to Felix's sunshine personality: he's an anxious mess, afraid and insecure, and my heart broke for him. Like Felix, he's been through quite a lot too, and seeing him blossom throughout the novel, seeing him learn to trust himself and his wolf, was freaking amazing. I loved him so much, and I loved Felix and Declan together even more.

< “No. We’re never doing that again. I could hurt you.” Felix rolls his eyes. “ Anyone could hurt me. I could go outside and get hit by a car. That’s just, like, part of life.”
“I have fucking claws ,” Declan says in exasperation.
“Ugh, fine, then we’ll get those chains you mentioned before and put you in cuffs. Then I can ride your dick with no threat of getting clawed up.” Declan looks at Felix like he’s grown a second head. Felix is getting used to that look. “You’re fucking crazy.” >

Their relationship was the cutest thing ever: respectful, soft, gentle. They have a few issues to begin with, but I loved seeing them work through them and around the boundaries each of them set.
Also, their dynamic is literal fire. Despite the soft, light-hearted atmosphere and the cozy vibes, when they finally give in and get together... well, the steam was freaking steamy. I blushed and I swooned and I kicked my feet and I screeched. I was OBSESSED with how hot they were for one another, and I loved how Kay Claire incorporated the paranormal elements and Declan being a werewolf into it. Will I ever tire of reading shifter romances? I think not. Give me any romance with a knot, and I'll be happy.

Horniness aside... I loved the cozy atmosphere, and I loved the setting (who do I have to pay to go and live in a town like Nimblyford?) and I loved every single side character. Wanda and Drew were fantastic, and I LOVED YASIN SO DAMN MUCH, he was the best. I hope the author decides to write more in this universe, because I really want to see them all again.
I also loved the writing, and I LOVED the illustrations this book goes with. It added something even more special to an already special book, and the art was seriously gorgeous, as is the cover.
"The Full Moon Problem" is a fairly chunky book, and maybe some descriptions and scenes could have been whittled down a smidge, but I think in some ways it added to its charm. Despite the length, this romance flows like a freaking dream, and I can't believe I managed to finish most of it in two short sessions, work and studying be damned.

I wholly recommend this book: it's out tomorrow, and I'll probably be screaming about it for the foreseeable future. I loved it to bits, and everyone should read it: it's got magic, it's got magical trans rep, it's got wolves and lots of freaky steam, and it's got a romance that will absolutely steal your heart. GO AND READ IT!

TWS/CWs: grief and death of family members, transphobia, discussions of Alzheimer's and cancer, panic attack.

Many thanks to the author for the ARC. This is my honest review.
