Cover: I haven't seen anything this awesome for a while. Look, there's Rosie in the corner.

Kyra never wanted to be a Seer. She's a Master Potioner and a highly respected one at that. But when she has a vision of her best friend, Princess Ariana, destroying the kingdom, she knows what she had to do.
A failed assassination leaves Kyra alone and friendless. With the help of her potions kit, a handsome rogue named Fred, and a magical princess tracking pig, it's up to Kyra to save the kingdom. No matter what the cost.
Ariana is my favorite character. I expected her a cookie cutter rebel princess.

I don't want to get married, I want to stay single and let my hair flow in the wind as I ride through the glen firing arrows into the sunset!

No. She likes adventures and knows how to use a throwing dagger, but she has an actual personality. She's the type of girl who would cut her own hair to make a false mustache just because she can. It's interesting to see the princess as a threat to the kingdom.
Poison is supposed to be set in your typical medieval European fantasy kingdom. They've got swords, queens, castles, and walking is the primary mode of transportation. Kyra stops in the nearest inn whenever she's not walking. One of the inns has a concierge. Another has a full kitchen with pots and pans in Fred's room. The dialogue is anachronistic too. Kyra uses the words guy, mom, and scram. Then they start throwing water balloons.
But hey, I like poison filled water balloons as much as the next girl. And Rosie the tracking pig made up for it. So did Kyra and Fred. Their relationship is so real. When Kyra thinks the smartest thing she can do is ditch Fred, she's right. Ruggedly handsome young rogues aren't the safest company. When she later realizes she's made a mistake, she's right too. Ruggedly handsome young rogues are often the best company you can hope for. He's not Sir Perfect, at your service whenever you need it. He's a real person with his own goal and secrets. Some of them are a threat to Kyra.      
Poison is an intriguing, twisting fantasy novel.
