Percy hadn't lost the habit of working all the times. Of course, he had lost the habit of being in his office day and night, which only meant that more and more papers were making their way home, some covered in spells that wouldn't allow anyone, not even Cass to read them.

Cass was coming back from that woman's house and Percy had a feeling that any sort of calm was about to evaporate.
