Mood and tone of quinceañera text

This story has 2 moods, because the story changes according as it advances, but the only things that did not change it´s the tone,  the tone remains the same. At the beginning we can see a mood of sad (but just a little bit) because she wanted a a party as her sister had, but as her father lost his job, she did not get, by the same reason, she did not get the cellphone that she wanted. But when she received a recipe book, and her grandma explained her about what she can do with the book and where this book came from, she changed her mood to interested. We can see the tone does not esplained us a lot about some things, that´s why I infere that the tone it´s misterious, because we don´t know if she at least recive the cellphone that she wanted, also the story does not esplain us about the reaction of she after her grandma explained her what she can do with the book
