Another Riddle

Hello!
I've got another riddle for everybody. Comment if you think you have the answer!!

In marble walls as white as milk,
Lined with skin as soft as silk,
Within a fountain, crystal clear,
A golden apple does appear.
No doors are there to this stronghold,
Yet thieves break in and steal the gold.
What am I?

This is one of the harder ones. But PLEASE guess!!!!
Oh, and please guess at the other riddle I posted on this blog.
Thanks!

At last....

As our first year of CHB comes to a close, I have a bittersweet feeling in my heart. While I will surely miss you all each Thursday, we had so many fun times and great memories from this year. And, we cannot forget about the summer kayak trip we have planned!!! Thank you to AO for helping get this set in motion!

I already have a TON of ideas for next year...games, secret symbols, Code of Honor, a CHB handshake, and many more activities. Please remember to do your best and be the best Demi-God you are. 

Feel free to share any summer half-blood moments you may run across during the next three months. Keep your eyes peeled and free of the MIST...remember we see what most others cannot. 

Oh, and be sure to keep checking this blog site! I have a few other [possible] summer activities lined up if we can make them all happen. 

And can someone PLEASE help me to figure out what house/cabin I belong to?!?!?!?!
