Hodder & Stoughton publisher Mark Booth has bought the novel Boyzone singer Stephen Gately was writing before he died last month.

Booth bought U.K. and Commonwealth rights to the "magical fantasy" title "The Tree of Seasons" in a deal brokered by Piers Blofeld at Sheil Land on behalf of Rosemary Reed and Caroline de Wolfe of Backdoor Management. Blofeld said Hodder paid "a very healthy advance".

Breda Purdue, managing director of Hachette Ireland, acquired Irish rights. It will be published in hardback in April 2010.

Gately's partner, Andrew Cowles, will work with members of Boyzone to finish and promote Gately's final work. Promotion will include television appearances and signings. Sir Elton John, who was also a friend of Gately's, is writing the foreword.

"I was so impressed to see how much work and imagination Stephen had put into 'The Tree of Seasons' and it is heartbreaking that he didn't get to finish it," said Purdue in a statement. "We are very proud to be involved in publishing this wonderful story and we feel that it will reach the hearts of a generation of children and will be a lasting memorial to a wonderful young man."
