Storm From The Shadows,
Mission of Honor and
A Rising Thunder by David Weber.
Space opera, interstellar naval battles, and political intrigue in Weber's "Honor Harrington" series.
The first book of the Honor Harrington series,
On Basilisk Station , is available for free download from Baen Books. I remember reading this book many years ago and thinking,
Hey, this is pretty good.. Twenty years and twenty books later, this series based on the life of British Admiral Horatio Nelson continues to entertain.
I like Baen Books as they are DRM-free and they have many books available for free so you can get hooked. (like the drug dealers, the first dose is free.
)
Mister Monday,
Grim Tuesday, and
Drowned Wednesday by Garth Nix.
Arthur Penhaligon gets a mysterious key and must find the pieces of the Will, torn apart ages ago into seven sections. These are the first three books of the YA "Keys of the Kingdom" series. I like it so far.
