Nobody's Prize by Esther Friesner

If you were obedient and read the first book, I am glad to tell you that you can read this post without screaming at me for ruining everything. If you didn't read the book, stop reading this post RIGHT NOW! However I can direct you to a more suitable post for you, try Nobody's Princess by the same author. Then you may read this.
Now, enough with the warnings. This will be a little shorter since this book is basically the continuation of the other. Like, immediate continuation. The end of Nobody's Princess and the beginning of Nobody's Prize are both on the same day for Helen. Well, I'll do the best I can for you who didn't listen to me when I warned you, but can't guarantee you'll be safe reading this. Keep a glass of water right next to you just in case you faint.

When Helen decides to sneak onto the Argo for The Quest of the Golden Fleece along with the ex slave Milo, she discovers it's not easy disguising herself as a man and being called Glacus instead of Lady Helen. Firstly, her brother's can easily notice her familiar blue eyes and those long lashes. On top of that, if she does get figured out, her punishment will be nothing she ever experienced before. On the bright side, Helen was getting exactly what she wanted; an adventure. Also, Milo knew her secret, and was always there when she needed him the most.
He aides her in basically everything; from getting her a blanket to stay warm to keeping her perilous secret safe and sound.There is also something else to the story. It's called my favorite subject, otherwise known as romance. Helen meets a handsome sailor named Hylas. The only problem is--Helen's a boy too! Milo notices the faint trace of a blush creeping up on Helen's cheeks everytime Hylas comes near, he notices the stutters and anxiety. Milo finally realizes the real reason he is so protective over his lady; his queen. He loves her.

Eeeeeee!!!! Love! Doesn't it just make your heart vibrate with excitement? Doesn't it just make you feel warm and content in your heart? Don't miss this thrilling sequel to Helen's adventure. Helen's waiting for you, so don't keep her too long.
