A nice collection of ice themed add-ins. I really liked the ice elementals and felt this book was well themed. The cantrip is useful and something a bit better than some of the others available without being overpowered. Ice mirror also has a great flavor for arctic campaigns, and I could totally see this being used in any kind of fiction. The 14 spells, the bloodline, feat, domain, template, and creature are fairly priced. +0 CR templates are always loved. This is well-balanced for pathfinder and easily added.
The spell Blue Touch kinda got under my skin a little. I'm not fond of having wizards and sorcerers having healing spells, but this on is so limited in use, I just can't see myself using it ever compared to a cure light wounds potion or spell. I think the bloodline is too far inferior to the stock offered elemental bloodline [water] of the core rulebook. Also, I was thinking it would have been nice to have some spells not physically linked to cold, but emotionally so, like maybe a "cold hearted" spell making the target unsympathetic, immunity ot emotional effects, at loss of morale bonus and such.
The 2 CP:
I usually rate elemental spells on their ability to translate into the other elements (for example the orb spells in 3.5). The more elemental things like this the higher I'd wanna rate this. The ice elementals could easily be magma, acrid, or ionic. The same goes for the feat and template. In the future I'd like to see more spells, and would be happy to pay more for the extra content.
