After two years of planning the hottest quineaneras in Miami and beyond, the girls of Amigas Incorporated are facing their biggest challenge yet -- high school graduation. While Carmen and Jamie know exactly what they want, Alicia is on the fence. Should she go to the school of her dreams even if it means doing exactly what has always been expected of her? Or should she try something new? With so many decisions to make, Alicia is beginning to feel like choosing a school is like preparing for a quince -- without any of the fun. On top of it all, the group has gotten a mysterious request from a young woman who wants to throw the most secret of quinceaneras. The girl wants it to be so secret that she won't even tell them her name! Now the group must figure out how to throw the perfect party for a perfect stranger, nail the SATs, and figure out if there is anyone at the school willing and capable of taking on their business. Will it all work out? Or will the end of school mean the end of Amigas Incorporated?
