Brain ships Book

I LOVE any writing by Anne McCaffrey - she is one of my absolute favourite authors, and the Brain Ships series is a particular favourite with me. This volume contains 2 stories that I hadn't read before - both as collaborations with different authors.
PartnerShip (in collaboration with Margaret Ball) is in the style I remember and love, Tia (a very clever child, the daughter of 2 renowned archaeologists) contracts a disease that leaves her paralysed - once she becomes a 'Brain Ship' however, she realises more of her potential than she could possibly have dreamed. McCaffrey & Ball manage to have you laughing and crying on the same page and this is the style that I am used to with McCaffrey books.
The Ship who Searched (in collaboration with Mercedes Lackey) although in the style of McCaffrey seems to me to have been more influenced by Lackey - the plot isn't a classic McCaffrey plot and the compartmentalised chapter style is not one that I would necessarily attribute to McCaffrey. The story works well though, but is not one that will remain with me like so many of her other books.
