Scottish themed poetry book and children's book

I have published a few books on Amazon.  One is a book of my poetry, mainly Scottish themed dealing with historical battles. (Poetry, A Collection).  The poems include a few about the battle of Culloden in 1746.  Another highlights the battle of Banockburn 400 years previous.  There is a Wallace poem, a Robert the Bruce poem and of course Bonnie Prince Charlie.  I am of Scottish decent and love the history.  Therefore I love writing about it. 

The other book is a Scottish themed, fully illustrated children's book.  It is basically a 900 word poem. (Magic Bagpipes and the five Jelly Tykes).

I published on Amazon through Kindle Direct Publishing.  I did this for the main reason that I could hold an actual book of my writings in my hand and not just a binder of pages put together.  When published you can order your own copies very cheaply.  The poetry book costs me $4.00 including the shipping.  Where else can you get your own book published for under $10?  It is also available for anyone to buy, but don't expect to retire on your book sales!
