Urban fantasy (possibly young adult) - family of witches, young woman sneaks downstairs to witness family doing ritual?

During plays, I don't let myself buy new books. Otherwise I'll completely ignore my script in favor of adventures. Well, I'm starting to pick up the ones I was interested in (and read the amazon preview for)... found all but one:

It's a novel about a young woman, maybe teenaged. She has a large family. To my knowledge, she's Hispanic and lives in the United States, but it doesn't specify. Her entire family are witches. Specifically, towards the end of the amazon preview (if that helps?), the young woman comes downstairs to find her mother and aunts doing a ritual with drums and chanting.

I can't remember her name, or what the ritual was about... I feel so guilty. I adored the preview. I am so excited to buy the book, but I just can't find it!

Please help.

Labyrinth Lost by Zoraida Cordova or possibly the sequel Bruja Born that came out earlier this year?
I haven't read them, so am just guessing based on plot summary...

Yay! Glad I could help.

It's been driving me crazy. I'm glad you were there!
