I just pre-ordered it from Amazon.com. It has vocab words in bold print that are defined in the "What that Word?" glossary in the back and it is full of academic science terms.
The story is about eight teens from diverse backgrounds who become trapped together inside of the magma chamber of a volcano. The teenage students are from El Salvador, Vietnam, Korea, South America, India, Morocco, Switzerland, and Mali. A friend of mine reviewed the book and read some of it to his intermediate language level class. He said they really liked it because of the love, humor, multiculturalism theme, and there are many issues they could related to (change in family life, crossing the Rio Grande to the US, teenage love interests, etc.). Supposedly there is a teacher reproducible activity book with grammer, reading, writing, science, and math worksheets and projects that relate to the novel that is coming out at the end of the summer. Certainly worth taking a look
! Has anyone else read it yet?
