The Outcast (the prequel novella to Scottish Lasses) by Glynnis Campbell
SCOTTISH LASSES...Meet the lasses in the world of Mary Queen of Scots...Like the Scottish thistle, they're lovely yet tough, beautiful yet prickly, and only the strongest and wisest heroes are able to elude their thorns to discover the tender blossom within.
Lachlan Mar, a disfigured and broken Scots warrior, doesn't believe anything can mend the wounds of war until Alisoune Hay, a brilliant and beautiful young lass, stumbles into his cottage and his life, healing his hurt and his heart with the most magical power of all—love.
