[Q]: The book begins in an unnamed Syrian city with  a teenage boy  Tareq  surrounded by his bustling  tight-knit family . It details  Tareq 's excruciating journey  leaving behind people and places  he  loves  almost from the very moment a bomb hits  his  family's home.
On the day that  Tareq 's home is struck by a bomb 
Tareq  was having a normal day with  his  family.  His  mom was cooking in the kitchen   his  grandmother was enjoying a small glass of tea   his  little brothers and sisters were playing and watching TV — just the typical day in their lives. And that typical day is destroyed by an airstrike.  He 's sent to the hospital where  he  does get some good news that  his  little sister is alive. But then a doctor takes  him  to a room and  he  sees  his  two 6-month-old little brothers dead on a gurney. And it seems very dark  but it's a situation that happens all the time  and really it's based on real characters  including those twins. I've seen pictures of the twins laying on the gurney  and it's the sad truth.
And for  Tareq   the character in my book   he  goes to Turkey.  He 's a second-class citizen there.  He 's going to go to Europe.  He 's going to be a second-class citizen there. There are people who don't want  him . There are people who fear  him   despite  him  being the one who's really afraid.
[A]: Tareq

[Q]: "An American first: a president who was obviously mentally ill the moment  he  took office  " Krugman  tweeted along with a New York Times report that Trump brought up debunked claims that millions of people voted illegally in the election  causing  him  to lose the popular vote  during a Monday night meeting with Congressional leaders.
 Krugman  has criticized Trump repeatedly since  his  election â questioning Trump's business conflicts of interest   his  Cabinet nominees  the involvement of Russia in  his  election  and more. But this is the first time  Krugman  called into question the mental fitness of the president.
 Krugman  has also been critical of Comey  arguing that Comey's letter to Congress regarding the renewed investigation into Hillary Clinton's use of a private email server swung the election in Trump's favor.
 Krugman  highlighted part of a Washington Post article about Trump's attitude after the election. "Read it and shudder " he wrote.
In subsequent tweets   Krugman  said that despite Trump's best efforts  the growing difference between increasing US interest rates due to rate hikes from the Federal Reserve and the interest rates throughout the rest of the world would increase the strength of the US dollar. A strong dollar would be harmful to US manufacturing  offsetting any pro-manufacturing policies from Trump   Krugman  said.
