Now this is a tough one. I've never read with cookie, so I don't know. However, I've read more often than not that you need at least 30 minutes with her and she rambles a lot and doesn't make sense and sometimes leaves a person confused. So, based on that, I'd skip out on her.
Kira is great with picking up current thoughts/energies. She's a stellar empath. That's for damn sure. BUT, I'm gonna have to say, if it were me, I'd go with Kisha. 1st of all, she's cheaper and you get more for your money. Second, she can see further out. She may not be like super super empath but if you're more looking for what events are to occur rather than current thoughts and feelings, I'd go with Kisha. However, if you're looking for more "what's he/she feeling right this second and in the near future", go with Kira. So the real question is, what kind of answers are you looking for?
