Any macro book suggestions?

[Fotografer]

I recently bought a Tamron 90 macro lens and I have instantly realised that macro is harder than I thought! I would love to get a book that is specifically focuses on macro and also using macro lenses. I couldn't really find that much information on the internet, as most is more about how you can get decent macro with a normal lens.</p>
<p>Any suggestions on books?</p>
<p>I saw on Amazon that Digital Macro Photography by Ross Hoddinot had pretty good reviews, or Close-Up and Macro Photography by Adrian Davies.</p>
