Hi Plant Lovers! My name is Martin Thearle and I have been collecting Hoyas for 7 years. This book is a record of the knowledge I have collected, both from my own experience as a collector and discussions with other collectors and Hoya lovers throughout the world. I hope you enjoy it and benefit from it. The cost is $65.00 + Australian postage charges. If you are interested in purchasing the book please send your details to me at the address listed below. Thank You. martinthearle@hotmail.com                                 Martin
