If you guys want to read SoS 2, then you can go here.

My opinion:

Its a very interesting and quasi mystical story and I have to agree with Dark that it most probably takes place after the HoO. I also think that the Serpents's Shadow (KC) takes place about 2-3 months after the Blood of Olympus. The story is pretty mysterious and the hidden enemy is also pretty obvious in the end too. Sadie was great, but Annabeth... Man its getting annoying whenever Annabeth starts chit chatting with some seriously powerful (and equally dumb) enemy to know his/her plans. Serapis was amazing though with his cool backstory and the Greek-Egyptian fusion and all. And I also like that Annabeth got her stuff back.

Another thing is in the Son of Sobek, Percy decides to keep the encounter a secret. Why the heck does he always have tell everything to Annabeth? Can't he keep even a single secret for himself? Anyways, looking forward for a sequel. Rick is doing a really good job with these crossovers, although this whole Greek-Roman-Egyptian thing is giving me a headache.
