agents are listed on
www.wga.org [writers guild of america] and at
www.aar-online.org [assoc. of artists' representatives]
most well-established agents won't be interested in a single book by a new writer, since they can't make much on such a sale... some do, however, so you'll have to find those who are open to queries from new writers...
but, be careful to avoid the many fakes who call themselves 'agents' or 'managers' and charge a reading fee or anything at all... real agents only get paid AFTER they SELL your work, and they will not offer to help you 'fix' your ms for a fee, either... anyone who asks for a single penny before selling your book is a con artist and should be avoided...
you may do better querying publishers directly... in your case, small independent presses that specialize in markets your book will fit... you can google for lists of publishers...
in both cases, be sure to check out the agency/company carefully, to make sure it's legit... you can find warnings on preditors & editors:

do be sure your ms is ready to be submitted... i see english errors in both your post and on your site, so it would be a good idea to have someone knowledgeable take a look at your ms before sending out queries...
you will also need a very good query letter and synopsis, as well as a chapter outline and 3 sample chapters, to send any who show interest in your work...
i wish you the best of luck...
namaste... love and hugs, maia
