This was a really good read but ultimately too sad for my tastes. Shortlisted for the Whitbread Award. Anne is 15 and skinny with no boobs and friends with a girl, Mel, who is well-endowed and also goes through dates and boyfriends like tissues. A new neighbour shifts in and turns out to be Adam Simmonds, who has SCID, Severe combined immunodeficiency. It means he has no natural resistance to bacteria so any mild infections could kill him. In the past such people used to die soon after birth but now they live longer, though rarely to his age, we're told. Basically, he lives in a big plastic room. After an initial embarrassing encounter, Anne decides to do a project on Adam and they become friends, then decide to be boyfriend and girlfriend. Adam is a really nice guy, though he has a few personality quirks from having socialised little in his life. He and Anne really fall in love, but then for his 16th birthday she arranges for him to go to a movie in his portable bubble and he becomes quite famous and gets a bit arrogant and gets her to go out and try things he can't do, like galloping a horse. Then he asks her to try sex, pretty much, partially also as he feels he is holding her back and she gets so angry she starts dating Tony, a nice guy who has had a lifetime crush on Mel. They have a pretty physical relationship, which she enjoys but when it comes to the crunch she can't sleep with him because she loves Adam. She felt more touching Adam's hand through plastic than making out with Tony. But now Adam is in hospital; they think they might be able to help him by transplanting some bone marrow. He and Anne reunite and he has the operation but then he goes downhill, so he comes out of the bubble for a couple of days and for the first time in his life is able to touch people and he and Anne have a night together. Then he dies and there is the grieving process to go through. He wants her to remember him but let him go, and live as he couldn't, and she does this by symbolically releasing the balloon he gave her into the sky.
