This is a cute little niblet of shifter romance. 
 Lon is an otter shifter, and he NEEDS to shift regularly in order stay copacetic. He chooses to do this because indoors + otter = MESS! Lon is an experienced snowboarder and like and self-respecting Coloradoan, he hijacks his powder by boarding down ungroomed backslopes. I found this to be hysterical. Also, side note: my one and only downhill skiing experience was at Eldora, one of Lon's fave haunts. 
 While boarding he often ditches his clothes in the deep pines and gives his otter room to play. He meets with Corey, a fellow backsider and econ professor, one afternoon, and helps Corey reclaim an errant board. In return Corey drives Lon back toward Boulder--they hit it off, and hit the sheets. It's all good. 
 They like each other and decide to make plans to repeat, and eventually date. It's still all good--with Corey none the wiser to Lon's otterness, and remarking to Lon how much he adores the frisky otter he often sees belly sliding down their slopes and frolicking in the creek. Lon's appreciative of the admiration, but knows he's got to keep his secret. 
 Until the unthinkable happens--Corey's got to leave the slopes early one day, well before Lon got his otter on, and the results are furry. I loved being in Lon's otterbrain. He's such a rascal. And Corey's the best man he could have encountered. Even if unexpected otter boyfriend + Cheerios = disaster. 
 As an economist, Corey's used to dealing with sums and balances. He's found a catch in Lon, and he's sure that being a couple requires flexibility. And, really, what mammal is more flexible than an otter? It is a sweet little story, with a bit of steam and fuzzy math to adore.
