The Lightkeeper's Daughters by Jean E. Pendziwol

They live on an island and keep the lighthouse's light burning during storms or fog and for late night navigation.  It seems like the family would be insulated against unfortunate or bad situations but that's not true.  For a family with four children, there's enough heart ache to fill the whole lighthouse.  They have secrets...

Harper and Edelweiss allowed me to read this book for review (thank you).  It will be published July 4th.

The story begins with a young girl who has gotten herself in trouble by spray painting a dragonfly on the nursing home's fence.  She has to do community service to make up for it and it happens to be fixing the graffiti and other maintenance work at the home is her punishment.  She can do that; it's not bad labor.  But she never expects to meet an old blind woman who has a tale to tell.  Especially when that tale comes around to answering some of her own questions...

Lives get mixed up, some get lost, and the survivors still have questions in their minds.  When the old lady's brother goes missing and they find several of her father's journals, she asks Morgan to read them to her.  She does and it contains the core of the story.  There's still one journal missing but it's found before the end of the story.  

After the secrets have been told, Morgan has a new life ahead of her.  She's learned a lot from the tales the old woman has shared with her.  She even learns more of her own background.  She's pretty centered in life now and will carry on the tradition of the women from the lighthouse: Be strong, be tough, be true to yourself.
