Revealing the Real Dr. Robinson [EPUB ebook] 

Those who work with Dr. Ben Robinson see a compassionate and brilliant doctor. But when he closes his eyes at night, he is haunted by the silence of the Argentinean jungle—fragments of his previous life invade his thoughts….Until a whirlwind arrives in the shape of beautiful Shanna Brooks, with her zest for life and "glass half-full" attitude, and Ben is forced to look at the world through her eyes and let down his guarded mask.
