The book trailer for Samantha Wilcoxson's book Plantagenet Princess Tudor Queen, proves that simple can be best.
Here we have no flashy special effects, voice-over, or silly fonts. The sparkly floating lights lend just enough of a mysterious quality, and the text says enough to tell us what the story is about. The use of images is spot on.
I especially like the choice of music, its rise and fall, and how it times out perfectly to the end of the trailer.
The book cover appears at both the beginning and the end - a must!
