Beyoncé delivered the ultimate surprise holiday gift on Thursday night when she released a 14-track self-titled album featuring an unexpected guest: Nigerian writer Chimamanda Ngozi Adiche, whose latest novel "Americanah" is atop many year-end reading lists.

The singer dropped the album on iTunes without any promotion, save for a 15-second Instagram video. And if that's not enough, Beyoncé's calling the project a "visual album" that's meant to be experienced through 17 surprise preview videos for the new album. Ngozi is on a track called "Flawless."
