First Howl & Second Howl
Found these two free reads on the author's site. They're basically just a small continuation of Wolf Signs and Wolf Flight featuring the four main characters. Both stories happen simultaneously, just as the main ones did.
It's been nearly a year since Signs and Flight. Both Robyn and Missy have both given birth nearly two months ago. Robyn had baby girl, Kara. Missy delivered baby boy, Jamie.
Now, both couples are in need of some New Year's Eve lovin'.
