Mothball Magic - Rena Rocford

She's going to save the world even if she breaks a hip doing it.

Ruth has been there and done that. She's already saved the world in WWII, when magic was locked away forever. So, when it inconveniently comes back in the middle of cooking dinner, seventy years later, Ruth must assemble a team of the mightiest geriatric magic-users left in the world to find out what caused it.

But this isn't like sneaking behind enemy lines when they were younger. Just missing her heart medication might be a bigger danger than facing down the fae. Old witches and wizards without their powers are just old ladies and men. They might live longer, but they're still only human, with grudges that go back decades.

It's the Golden Girls meets the Dresden Files! Four geriatric people must stop the Queen of Winter from taking over the world, in Mothball Magic by Rena Rocford!
