He wants to play football even though he weighs 127 pounds and is small in stature. He also wants to challenge his history teacher Mr. Lambeer, because he likes to teach his students biased material and Ben feels very strongly against.  Ben repetitively challenges Mr. Lambeer that it aggravates him and threatens him to fail him but Ben does not care because he knows he will not be attending college because of his illness. Well football season goes extremely well and Dallas and he became very close and the relationship with his brother grows stronger. Ben finally comes to grip with his illness and tells the people he loves because he feels horrible for him not to tell them. At the end they come and help and love on him on his final days. 
This book is good to teach on the basis of a teenager making hard dissension about life and love. This is good to read in the high school because of the tough subject of death and responsibility. 
Other books to read with similar plot that are highly recommended the following books because they deal with the subject of death and responsibility.
