Oolite Bulletins

hi.

i'm looking for judas unchained by peter hamilton in epub format. it used to be on the ibooks store, but they've removed it, and now i can't find it anywhere. can anyone point me in the right direction?

yes, i know i could get it for the kindle, but i don't want it for the kindle, i want it for ibooks.

I have it as a PDF, but no ePub, sorry. All my google searches have turned up the title on torrents, but not as purchasable ebooks.
