The Light in Their Eyes. Maxwell Family Trilogy, #2

Although peace has been declared, the war keeps on taking... Elizabeth yearns for adventure. She strives for a life outside the confines of marriage, while Robbie, shackled by his own fears, is desperate to find a sense of purpose. Returning home from war in New Guinea, the once-charismatic Robbie's grip on life becomes tenuous. Trapped within his mind, haunted by what he has seen and done, alcohol offers the only relief.
He meets Elizabeth, a young beauty who captivates him and promises the serenity he craves. Despite her secret and his trauma that threatens their marriage, she digs deep to maintain her autonomy while doing all she can to keep him alive.
