Cloak Games book 4. Spoilers for earlier ones.
Nadia is given the simple task of breaking into an Elven noble's home to steal something. Things are going relatively smoothly when it's stolen from under her nose, and the alarms go off.
Some effort later, she extracts herself, discovers her master knows the other thief, and merely has to collect it from him before her deadline.
It involves an apartment in a pricey tower, doormen who aren't men, a conservation at cross-purposes with a suitable dramatic reveal, a special power of the title, some new magical artifacts, and more.
