Hehe... It's up there in the description "The Stone Rose" by Jacqueline Rayner. ...And just a small hint. It's abridged and actually quite a bit shorter, I believe, but the Audio Book is read by David Tennant
And no worries. I love the two of them as well! I started watching about three months ago and I'm caught up with New Who now... And I still cry whenever I think about Rose and Ten.
AW! Somebody filnally painted this scene!! I love it! Both the picture and the book! And I just looove when David reads it, this together with his voice.. agh! Pure awesomness! I also love "The Feast of the Drowned", (" Or maybe just bacause she's Rose."), "Only Human" (" You enjoyed that, didn't you.") and well, more like all of them, though I still have not read all. Such a shame I can't find time for it.. Oh, And I just love the moment in "The Last Dodo", when ***SPOILERS, I GUESS*** Martha mentiones pets, and the Doctor is like "You've never met Mickey, now, did you?" and then when you take this to "The End of Time pt.2" when we find out, Martha and Mickey are married, it just is so awesome! I love Mickey and Martha together, the're lovely!
With Ninth, Tenth, and even Twelfth in the picture, maybe.. just maybe you could have Eleventh in the TARDIS reaching out to the voice interface Rose while he's dying of poison from "Let's kill Hitler"? That would be so impressionable.
Alternatively you could draw him meeting the mysterious Bad-Wolf looking Rose ie the 50th anni... ^^
