First of all, the cover is amazeballs. Gorgeous! (Rounded up to four stars, just for the cover. :)
Interesting premise. Both authors parse out backstory in tiny pieces, which works for the length of the stories. While I don't usually mind info-dump, it took me a little while to appreciate the fast paced mating courtship. Both stories were concise, sexy, and created a world of puma-shifters that sounded intriguing. (Probably just me, but every time I read "Pantera" I kept imagining the rock band, which gave me the giggles.) Love the male characters' names though! Good start to a series.
